What does “irripetibile” mean in Italian?

Irripetibile means “unrepeatable” or “one of a kind” — something so singular it could never happen twice. It’s built like an equation: the negative prefix ir- (a form of in-) plus ripetibile (“repeatable,” from ripetere, “to repeat”) plus the suffix -ibile, Italian’s version of English “-ible.” In this clip, fans praising a beloved radio personality reach for exactly this word twice: unico, unico, irripetibile — “unique, unique, one-of-a-kind.”

That ir-/in- + verb + -ibile pattern is one of Italian’s most productive: indimenticabile (“unforgettable”), inimitabile (“inimitable”), irraggiungibile (“unreachable”). Once you spot the shape — negative prefix, verb stem, “-ible” tail — you can build or decode dozens of similar words on sight, in Italian just as in English.
