minute
The Italian word 'minuto' is used much like the English word 'minute' to refer to a unit of time equal to sixty seconds. It can also refer to a specific point in time or to express a short length of time.
A minute ago, we were talking about football.
In this sentence, 'minuto' is used to denote a time frame. Specifically, 'un minuto fa' translates directly to 'a minute ago', demonstrating the past tense structure used in Italian to indicate something that happened in the immediate past.
The train will arrive in a minute.
Here, 'un minuto' is used as a unit of time in a future context. The phrase 'Il treno arriverà in un minuto' gives an indication that the event (the train's arrival) will happen after a certain amount of time has passed.
I can't wait even a minute longer.
'Un minuto' once again represents a unit of time, but this time it emphasizes the speaker's impatience. The word 'nemmeno' intensifies the statement by suggesting that the speaker cannot wait even a small amount of time, as represented by 'un minuto'.
