🔍 In short. If you learn to italian predict irregular verbs from their infinitive, the whole verb system stops feeling like a memory game. Bere is really bevere in disguise, so the whole paradigm uses bev-: bevo, bevevo, bevuto. Verbs in -arre, -orre, -urre (like trarre, porre, condurre) are contracted infinitives that hide a longer Latin stem: tra(h)-, pon-, duc-. Once you know the trick, you can italian predict irregular verbs in their present, imperfect, future, past participle and even their compounds (supporre, comporre, tradurre, introdurre) on first sight. This B1 guide shows you how to italian predict irregular verbs from the infinitive, with a cheat sheet, two mini-tasks, a Trapani salt-pans dialogue, and a quiz.
By the end you’ll stop memorising tables verb by verb and start reading infinitives like a native: with a small map in your head that turns “irregular” into “predictable, once you know the family”.

Why you can italian predict irregular verbs at all
Open any verb table and Italian looks like a minefield: bevo from bere, pongo from porre, traduco from tradurre, traggo from trarre. The shapes don’t seem to match the infinitive. The good news, and the heart of this guide on how to italian predict irregular verbs, is that almost all of these “irregular” shapes follow a small set of historical patterns. The modern infinitive is a contracted form, and the conjugation simply preserves the older, longer stem the speakers of Dante’s time still used.
Once you know the trick, you can italian predict irregular verbs as a system rather than a random list. You learn one family, and a whole crowd of compounds comes along for free. Learn porre and you’ve also learned comporre, supporre, proporre, opporre, esporre, imporre, disporre. Learn condurre and you’ve learned tradurre, produrre, ridurre, sedurre, dedurre, introdurre. The skill is recognising the family from the ending: -arre, -orre, -urre. After that, the conjugation runs on autopilot.
In this guide we’ll look at the four big infinitive shapes that let you italian predict irregular verbs on sight: bere as a one-off contraction, then the -arre, -orre, -urre families, then dire and fare as honorary members. Each one becomes easy once you mentally rebuild the longer infinitive.
Bere: the verb that’s really bevere
Of all the italian irregular verbs you might want to italian predict irregular verbs from, bere is the friendliest puzzle. The infinitive looks like a bare three-letter word, but the conjugation throws a -v- at you everywhere. Bevo, bevi, beve, beviamo, bevete, bevono. Bevevo, bevuto, beverò. Why the v?
Because the older Italian infinitive was bevere, which itself comes from the Latin bibere. Dante and Boccaccio still wrote bevere, and several southern dialects keep that older form today. At some point the modern infinitive lost its middle -ve- for ease of pronunciation, but the rest of the paradigm held on to the older stem. So the trick is simple: when you see bere, mentally replace it with bevere and conjugate it as a regular second-conjugation verb. The forms fall into place.
- Adelaide beve un caffè freddo guardando i fenicotteri sopra le vasche delle saline.
Adelaide drinks a cold coffee while watching the flamingos above the salt pans. - Da piccoli bevevamo l’acqua della fontana di Piazza Saturno senza pensarci due volte.
When we were little we used to drink water from the fountain in Piazza Saturno without thinking twice. - Severino ha bevuto tre bicchieri di passito di Pantelleria al matrimonio del cugino.
Severino drank three glasses of passito di Pantelleria at his cousin’s wedding.
The same rebuild works for the future: bere would seem to give bererò, but the actual form is berrò, with double r. This belongs to a small group of irregular forms whose future stem doubles the r, and it’s another spot where you can italian predict irregular verbs once you know the shortcut: bere → berrò, venire → verrò, tenere → terrò, volere → vorrò, parere → parrò. Different verbs, same shortcut: drop the e before -rò, and let the consonants slide together into a doubled r.
The -arre family: trarre and its cousins
The verb trarre (to draw, to pull, to derive) is the head of a small but important family that lets you italian predict irregular verbs in one shot. Its infinitive ends in -arre, which is the giveaway: any verb ending in -arre follows the same template. The underlying stem is tra- (from Latin trahere), and it picks up a doubled -gg- in the first-person singular and third-person plural of the present.
| Person | trarre (present) | Translation |
|---|---|---|
| io | traggo | I draw / I pull |
| tu | trai | you draw |
| lui / lei | trae | he / she draws |
| noi | traiamo | we draw |
| voi | traete | you (pl.) draw |
| loro | traggono | they draw |
The list of compounds gives you a lot of mileage for one rule: attrarre (attract), distrarre (distract), estrarre (extract), contrarre (contract), sottrarre (subtract), protrarre (prolong), ritrarre (portray, retract). Every one of them sits on the same paradigm. Learn traggo, trai, trae, traiamo, traete, traggono once, and you can immediately produce estraggo, estrai, estrae and contraggo, contrai, contrae without consulting a table.
- Adelaide trae ispirazione dai mulini a vento delle saline per la sua nuova serie di acquerelli.
Adelaide draws inspiration from the windmills of the salt pans for her new watercolour series. - Il museo estrae i blocchi di sale dalle vasche più vecchie soltanto a fine agosto.
The museum extracts the salt blocks from the oldest pans only at the end of August. - Severino, mi distrai mentre cerco di leggere il pannello sui pesci della tonnara!
Severino, you’re distracting me while I’m trying to read the panel about the tuna trap’s fish!
🎯 Mini-task #1. Predict the io and loro present forms of these compound verbs.
- estrarre (to extract): io ___, loro ___
- sottrarre (to subtract): io ___, loro ___
- attrarre (to attract): io ___, loro ___
- contrarre (to contract): io ___, loro ___
- distrarre (to distract): io ___, loro ___
👉 Show answers
1. estraggo, estraggono
2. sottraggo, sottraggono
3. attraggo, attraggono
4. contraggo, contraggono
5. distraggo, distraggono
Every -arre verb takes the same -ggo / -ggono shape in the present, because they all share the underlying stem and the compound doesn’t change the paradigm.
The -orre family: porre, supporre, comporre
Next in our tour of how to italian predict irregular verbs are the -orre verbs. The head of the family is porre (to place, to put), from the Latin ponere. Once you see that the hidden stem is pon-, every “irregular” form turns into a plain second-conjugation pattern in disguise.
| Person | porre (present) | Translation |
|---|---|---|
| io | pongo | I place |
| tu | poni | you place |
| lui / lei | pone | he / she places |
| noi | poniamo | we place |
| voi | ponete | you (pl.) place |
| loro | pongono | they place |
The pattern that lets you italian predict irregular verbs in this family is on full display: the first-person singular and third-person plural get a velar -g- inserted before the ending (pongo, pongono), exactly like vengo / vengono, tengo / tengono, rimango / rimangono. Everywhere else, the stem is plainly pon-: pone, poniamo, ponete. The infinitive porre is the only place where the old -n- dropped and the two -r-s collided.
The compound bonus here is huge. Each of these verbs follows the porre paradigm without exception: comporre (compose), supporre (suppose), proporre (propose), opporre (oppose), imporre (impose), esporre (expose, exhibit), disporre (arrange), posporre (postpone), sovrapporre (superimpose), presupporre (presuppose). That’s ten verbs for the price of one.
- Severino pone la macchina fotografica sul muretto bianco prima di scattare la foto al tramonto.
Severino places his camera on the white wall before taking the sunset photo. - Il direttore del museo propone una mostra dedicata al corallo trapanese per la prossima primavera.
The museum director is proposing an exhibition on Trapani coral for next spring. - Adelaide e Severino hanno composto un piccolo album di foto da regalare ai cugini di Modena.
Adelaide and Severino have put together a small photo album to give to their cousins in Modena. - Suppongo che la guida del museo parli anche francese, viste le comitive in arrivo.
I suppose the museum guide also speaks French, given the groups arriving.
The -urre family: condurre, tradurre, produrre
The -urre verbs are the largest and most useful subgroup when you italian predict irregular verbs at B1. They all come from the Latin family of ducere, and the hidden stem is -duc-. Modern Italian dropped the -de- in the infinitive but kept the -duc- everywhere else. So condurre is morphologically conducere, and the present is built on conduc-.
| Person | condurre (present) | Translation |
|---|---|---|
| io | conduco | I lead / I drive |
| tu | conduci | you lead |
| lui / lei | conduce | he / she leads |
| noi | conduciamo | we lead |
| voi | conducete | you (pl.) lead |
| loro | conducono | they lead |
Spelling has a small twist worth flagging: the c of -duc- is hard before o and a (conduco, conducono, conducano) and soft before i and e (conduci, conduce, conducete, conduciamo). It’s the same orthographic switch you already know from cucinare or vincere. The phonetics is regular, the spelling just has to track the sound.
Compounds in -urre are everywhere in everyday Italian, and they all conjugate exactly like condurre: tradurre (translate, traduco, traduce, traducono), produrre (produce, produco, produce, producono), ridurre (reduce), sedurre (seduce), dedurre (deduce), indurre (induce), introdurre (introduce, lead in), riprodurre (reproduce). Memorise one and you’ve got the whole set.
- Severino traduce per i turisti tedeschi le spiegazioni del salinaro sulla raccolta del sale.
Severino translates the salt-worker’s explanations about salt harvesting for the German tourists. - Domani conduciamo i ragazzi della scuola al Museo della Tonnara di Bonagia per la visita guidata.
Tomorrow we’re taking the school kids to the Bonagia Tuna Museum for the guided tour. - La cooperativa di Nubia produce ancora il sale a mano, senza macchinari moderni.
The Nubia cooperative still produces salt by hand, with no modern machinery. - Le piogge di marzo riducono la concentrazione di sale nelle vasche più esterne.
The March rains reduce the salt concentration in the outermost pans.
Dire and fare: the same trick, older form
Two of the most common irregular forms work on exactly the same principle as bere, and they let you italian predict irregular verbs through the same rebuild-the-Latin-stem trick: dire and fare. Both look short and rebellious, but their conjugations are built on a longer Latin stem that the speakers never gave up. The modern infinitives are contractions of dicere and facere, and that’s where the -c- in dico, dici, dice and the -acc- in faccio come from.
- Dire → underlying dicere → dico, dici, dice, diciamo, dite, dicono · imperfetto dicevo · participio detto · futuro dirò.
- Fare → underlying facere → faccio, fai, fa, facciamo, fate, fanno · imperfetto facevo · participio fatto · futuro farò.
The bonus, again, is the compounds. Dire shares its paradigm with disdire (cancel), contraddire (contradict), predire (predict), maledire (curse), benedire (bless). Fare covers rifare (redo), disfare (undo), soddisfare (satisfy), contraffare (counterfeit). All of them rebuild as dic- and fac- wherever the action of the verb shows up.
The single most useful rule for the imperfect
If you remember one thing from this guide on how to italian predict irregular verbs, make it this: the imperfect stem is the same as the second-person plural of the present. Take voi in the present, drop the -te, add the imperfect endings -vo, -vi, -va, -vamo, -vate, -vano. It works for almost every irregular verb you’ll meet.
| Infinitive | voi present | Imperfect (io) |
|---|---|---|
| bere | bevete | bevevo |
| trarre | traete | traevo |
| porre | ponete | ponevo |
| condurre | conducete | conducevo |
| tradurre | traducete | traducevo |
| dire | dite | dicevo * |
| fare | fate | facevo * |
* The two exceptions are dire and fare: the imperfect uses the longer Latin stem (dicevo, facevo), not the short dite, fate. Treat them as a small detour, then come back to the main rule for everything else.
- Quando ero piccolo, mio nonno mi conduceva al Museo del Sale di Nubia ogni sabato pomeriggio.
When I was little, my grandfather would take me to the Nubia Salt Museum every Saturday afternoon. - I salinari traevano il sale a mano con pale di legno fino agli anni Sessanta.
The salt-workers used to draw the salt by hand with wooden shovels until the 1960s. - Da bambina, Adelaide componeva piccole canzoni sui mulini delle saline e le cantava ai cugini.
As a child, Adelaide used to compose little songs about the salt-pan windmills and sing them to her cousins.
Predicting the past participle: -atto, -osto, -otto
Past participles let you italian predict irregular verbs in these three families with surprising ease, once you spot the family signature. Each ending corresponds to one family:
- -arre verbs → past participle in -atto: trarre → tratto, estrarre → estratto, attrarre → attratto, contrarre → contratto.
- -orre verbs → past participle in -osto: porre → posto, comporre → composto, supporre → supposto, esporre → esposto, proporre → proposto.
- -urre verbs → past participle in -otto: condurre → condotto, tradurre → tradotto, produrre → prodotto, ridurre → ridotto, sedurre → sedotto.
- bere → bevuto (regular second conjugation, once you remember the underlying bevere).
- dire → detto; fare → fatto.
So a B1 learner who sees a brand-new verb like protrarre (to prolong) for the first time can italian predict irregular verbs with no dictionary: present protraggo, imperfect protraevo, past participle protratto. That’s the predictive power that turns the whole list from a memory exercise into a system.
- Adelaide ha tratto ispirazione dalle vecchie cartoline della tonnara per il poster del museo.
Adelaide drew inspiration from the old postcards of the tuna trap for the museum poster. - Il fotografo ha esposto venti scatti delle saline al tramonto nella sala principale.
The photographer exhibited twenty shots of the salt pans at sunset in the main hall. - Severino ha tradotto in inglese tutti i pannelli del Museo della Tonnara di Bonagia.
Severino translated all the panels of the Bonagia Tuna Museum into English.
The future stem of bere, vivere, venire
The future tense gives you yet another way to italian predict irregular verbs, with its own small set of shortcuts. Most second-conjugation verbs drop the -e- of the infinitive: vendere → venderò, dovere → dovrò, potere → potrò. A handful go a step further and double the r:
- bere → berrò (and conditional berrei)
- venire → verrò
- tenere → terrò
- volere → vorrò
- parere → parrò
- rimanere → rimarrò
The -arre, -orre, -urre families are predictable in a different way: they drop one of the two r‘s and add the standard endings on the contracted infinitive itself. Trarre → trarrò, trarrai, trarrà. Porre → porrò, porrai, porrà. Condurre → condurrò, condurrai, condurrà. The double r is already in the infinitive, so the future stem is just the infinitive minus the e.
- Severino tradurrà la guida del museo per i visitatori francesi sabato prossimo.
Severino will translate the museum guide for the French visitors next Saturday. - Adelaide indurrà la madre a venire in vacanza a Trapani il mese prossimo, ne sono certa.
Adelaide will persuade her mother to come on holiday to Trapani next month, I’m certain. - Berrò un bicchiere d’acqua e mezzo prima di affrontare il sole delle dodici.
I’ll drink a glass and a half of water before facing the midday sun.
One family, dozens of verbs: the compound bonus
The single best return on investment when you learn to italian predict irregular verbs comes from the compound bonus. A compound verb (formed with a prefix like com-, sup-, pro-, ri-, dis-, tra-) keeps the simple verb’s paradigm without exception. There are no surprises. The prefix changes the meaning, never the conjugation.
| Family head | Compounds | How many free verbs |
|---|---|---|
| porre (pose) | com-, sup-, pro-, op-, im-, es-, dis-, pos-, sovrap-, presup- | 10+ |
| condurre (lead) | tra-, pro-, ri-, se-, de-, in-, intro-, riprodu- | 8+ |
| trarre (draw) | at-, dis-, es-, con-, sot-, pro-, ri- | 7+ |
| dire (say) | dis-, contrad-, pre-, male-, bene-, ri- | 6+ |
| fare (do) | ri-, dis-, soddis-, contraf-, sopraf- | 5+ |
| venire (come) | av-, di-, pro-, inter-, sov-, con- | 6+ |
Add it up: six family heads buy you over forty verbs you can conjugate at sight. That’s a much better ratio than memorising verbs one by one. Native speakers don’t store all these forms separately either: they hear esporre and instantly know it’s espongo, esponi, espose, esponevo, esposto, esporrò, because they’ve internalised the porre template.
🎯 Mini-task #2. Predict the past participle of each verb without looking anything up.
- introdurre (to introduce, lead in) → ___
- esporre (to expose, exhibit) → ___
- sottrarre (to subtract) → ___

2. esposto (-orre → -osto)
3. sottratto (-arre → -atto)
4. predetto (dire family → -detto)
5. soddisfatto (fare family → -fatto)
6. rimasto (this one breaks the family rule: rimanere has its own pattern, like rimangono / rimarrò / rimasto. A useful reminder that the system covers most verbs, not all.)

Dialogue at the Trapani salt pans
Adelaide and Severino visit the salt pans of Trapani-Paceco at the end of the afternoon, then walk on to the Museo della Tonnara di Bonagia. Watch how their conversation rolls through ways to italian predict irregular verbs from all the families above: propone, beviamo, traduce, conduce, ho posto, hai composto, tradurrà.
👱🏼♀️ Adelaide: Severino, propongo di fermarci un momento qui prima del mulino. La luce sta diventando rosa e l’acqua delle vasche sembra un altro pianeta.
Severino, I suggest we stop here for a moment before the windmill. The light is turning pink and the water in the pans looks like another planet.
👨🏼🦰 Severino: D’accordo. Beviamo un sorso d’acqua, qui il sole picchia anche alle sei. Hai portato la borraccia grande?
Agreed. Let’s drink a sip of water, the sun beats down here even at six. Did you bring the big water bottle?
👱🏼♀️ Adelaide: Sì, la conduco in giro da stamattina. Ho già bevuto metà. Senti, quel signore con il cappello traduce per il gruppo di tedeschi: si sente che è del posto.
Yes, I’ve been carrying it around since this morning. I’ve already drunk half of it. Listen, that gentleman with the hat is translating for the German group: you can tell he’s a local.
👨🏼🦰 Severino: Lo conosco di vista. Conduce le visite guidate al Museo del Sale di Nubia da almeno vent’anni. Mi sa che da giovane traeva il sale a mano insieme al padre.
I know him by sight. He’s been leading guided tours at the Nubia Salt Museum for at least twenty years. I think when he was young he used to harvest the salt by hand with his father.
👱🏼♀️ Adelaide: Bello. Allora domani propongo di fermarci anche al Museo della Tonnara di Bonagia, se ce la facciamo a partire presto. Lì espongono le reti antiche tutta l’estate.
Lovely. Then tomorrow I suggest we also stop at the Bonagia Tuna Museum, if we manage to leave early. They exhibit the old nets there all summer.
👨🏼🦰 Severino: Suppongo che apra alle dieci. Ho posto la sveglia alle otto, così facciamo colazione con calma. Hai composto la playlist per la macchina?
I suppose it opens at ten. I set the alarm for eight, so we can have breakfast at our own pace. Have you put together the playlist for the car?
👱🏼♀️ Adelaide: Quasi. Ho aggiunto i pezzi di Battiato che dicevi tu, e una cosa di Carmen Consoli che mio cugino mi ha tradotto in inglese per scherzo. Funziona meglio in italiano, devo dire.
Almost. I added the Battiato tracks you mentioned, and a Carmen Consoli song my cousin translated into English as a joke. It works better in Italian, I have to say.
👨🏼🦰 Severino: Te lo dico, le canzoni perdono qualcosa se le riduci. Domani al museo c’è anche una mostra di acquerelli sulle saline: traggono ispirazione dai colori del tramonto, come stai facendo tu.
I’m telling you, songs lose something if you reduce them. Tomorrow at the museum there’s also a watercolour exhibition on the salt pans: they draw inspiration from the sunset colours, the way you’re doing now.
👱🏼♀️ Adelaide: Allora dobbiamo andarci. La guida pensi che tradurrà anche in inglese?
Then we have to go. Do you think the guide will translate into English as well?
👨🏼🦰 Severino: Suppongo di sì. E se non lo fa, mi propongo io volontario. Le poche parole di inglese che mi restano dal liceo, le tiro fuori per i tedeschi nostalgici del mare di Sicilia.
I suppose so. And if he doesn’t, I’ll volunteer myself. The few words of English I have left from high school, I’ll dust them off for the Germans who miss the Sicilian sea.
👱🏼♀️ Adelaide: Sei un disastro, ma sei utile. Andiamo, il sole sta calando e voglio vedere i fenicotteri prima che si nascondano dietro il mulino.
You’re a disaster, but you’re useful. Let’s go, the sun is going down and I want to see the flamingos before they hide behind the windmill.
What to notice in the dialogue
- Propongo, propone, propongono: present forms of proporre, with the -g- insertion typical of the porre family.
- Beviamo, ho bevuto: bere conjugated on the hidden bev- stem, with the regular past participle.
- Traduce, ha tradotto, tradurrà: the same -urre verb across three tenses; the underlying -duc- appears in the present, the -otto ending in the participle, the double r in the future.
- Conduco, conduce, conducevo: condurre in present and imperfect, both predictable from the -duc- stem.
- Traeva, traggono: trarre imperfect (rebuilt from traete) and present 3pl (with the -gg-).
- Ho posto, hai composto, espongono: porre family in past participle and present, all built on pon-.

Learning to italian predict irregular verbs comes from seeing them as a system, not as a list. Read short Italian texts every day, underline the verbs in -arre, -orre, -urre and the family heads bere, dire, fare, and check whether you could italian predict irregular verbs on first sight. After a few weeks the prediction becomes automatic and the “irregular” label stops slowing you down. Pair this guide with the quiz below and revisit it once a month: each pass locks the patterns in deeper and makes it faster to italian predict irregular verbs the next time you meet one.

Frequently asked questions
These questions about how to italian predict irregular verbs come from real B1 learners online. The historical background is laid out in the Treccani vocabolario entry on bere.
Why is bere irregular if its conjugation looks like a regular -ere verb?
To italian predict irregular verbs like bere, treat the infinitive as a contraction: the older form was bevere, from Latin bibere, and the modern infinitive dropped the middle -ve-. The full paradigm still uses the older bev- stem: bevo, bevi, beve, beviamo, bevete, bevono in the present; bevevo in the imperfect; bevuto in the past participle. The only place where the infinitive’s short shape really shows up is the future, which doubles the r: berrò, berrai, berrà. Mentally treat bere as bevere and you can italian predict irregular verbs in this family as easily as any standard second-conjugation verb.
What do italian verbs in -arre, -orre and -urre have in common?
All three endings are contracted infinitives of older Italian forms that themselves come from Latin, and they let you italian predict irregular verbs across dozens of compounds. -arre comes from -ahere (trarre from trahere), -orre from -onere (porre from ponere), -urre from -ucere (condurre from conducere, tradurre from traducere). In each family the longer stem survives everywhere outside the infinitive and the future. So you get traggo, pongo, conduco in the present; traevo, ponevo, conducevo in the imperfect; tratto, posto, condotto in the past participle. Three patterns let you italian predict irregular verbs in dozens of verbs at once.
If I learn porre, do I really get supporre, comporre and proporre for free?
Yes. A compound verb in Italian keeps the simple verb’s paradigm without exception, which is exactly what makes it easy to italian predict irregular verbs from prefixed forms. Porre gives you pongo, poni, pone, poniamo, ponete, pongono; the imperfect ponevo; the past participle posto; the future porrò. Supporre is suppongo, supponi, suppone, supponiamo, supponete, suppongono; supponevo; supposto; supporrò. Same template, different prefix. The same rule lets you italian predict irregular verbs in comporre, proporre, opporre, esporre, imporre, disporre. Learning one head verb gives you the whole family.
Why is the past participle of trarre tratto and of porre posto?
The -arre family has past participles in -atto: tratto, estratto, attratto, sottratto, contratto. The -orre family takes -osto: posto, composto, esposto, supposto, proposto. The -urre family takes -otto: condotto, tradotto, prodotto, ridotto, sedotto, introdotto. These three endings are reliable enough that once you spot the infinitive’s family, you can italian predict irregular verbs at the participle level without checking a dictionary. The pattern is so strong that native speakers sometimes back-form a fake infinitive from the participle: the wrong form redarre exists in mistaken Italian because speakers try to italian predict irregular verbs in reverse, rebuilding trarre from redatto. The real verb is redigere.
What is the safest trick to find the imperfect of any irregular -urre or -orre verb?
Take the voi form of the present and replace -te with -vo, -vi, -va, -vamo, -vate, -vano. Producete becomes producevo, conducete becomes conducevo, ponete becomes ponevo, traete becomes traevo. This rule lets you italian predict irregular verbs at the imperfect with almost no effort, with two famous exceptions: dire uses dicevo (not divo) and fare uses facevo (not favo), because they rebuild on the longer Latin stem. For every other verb the voi-to-imperfect shortcut works the first time, which is why it’s the single best trick to italian predict irregular verbs at this tense.
Are these patterns reliable enough that I can guess a new verb’s conjugation?
For the families covered here, yes: -arre, -orre, -urre, bere, dire, fare and their compounds follow the templates almost without exception, which is exactly what lets a B1 learner italian predict irregular verbs at sight. If you meet protrarre, intercorrere, sovrapporre or riprodurre for the first time, you can confidently italian predict irregular verbs across their present, imperfect, past participle and future without a table. The system has small leaks (rimanere has its own pattern: rimangono, rimasto, rimarrò), but the families above cover dozens of high-frequency verbs. Treat the rules as a strong default for how to italian predict irregular verbs and let the rare exceptions surprise you only when they do.
