Italians are passionate and emotional, and so is our language. Interiezioni are common and fun words used for expressing an emotion.
An interiezione (or esclamazione) is an inviariable part of a sentence (no masculine / feminine, singular / plural) expressing a sudden emotion. It comes from the Latin interiecere, “to throw in the middle”, because it comes suddenly, in the middle of a conversation, usually followed by an exclamation mark.
It is quite difficult to associate a particular emotion with each interiezione, or even translate a single one. I’ll try anyway.
