"Grullo" The ultimate Florentine word. It means a person who is silly, un-clever, but also a bit incautious. "Oh grullo! Icchè tuffai, un tu vedi che piove?!!” (Dummy, what are you doing, can’t you see it’s raining?!!) This could be a typical Florentine phrase with which to communicate a strange or unusual action. In short, if they say it to you jokingly, don’t take it to heart; if you hear it said to you often, it’s not a good sign!
“Ma icchè tu dici!” The phrase you will hear most often once you arrive in the city. It means, "What are you saying?" and is used both as a question and as an exclamation, sometimes as a filler word.
"Bischero" This word literally means a person who is not very well educated or not very clever, who often uses inappropriate behavior. It is mostly used in a playful way. "Ho fatto una bischerata" means to have done something without thinking, resulting in failure.
"Trombaio" In Florence this word refers to a plumber. If you have to contact your landlord over a broken pipe, you will know whom to turn to.
“Arrivare dopo i fochi di San Giovanni” In Florence, in June, the patron saint San Giovanni Battista is celebrated. This festival in ancient times included tournaments, a horse race (remembered by Dante and Boccaccio) and a fair. At the end, there were fires, on which men and animals were blown up according to the tradition of blessing `for ignem'. "Arriving after the fires are out,” means arriving after all is said and done; too late.
“Senza lilleri, un si lallera!” An expression that you will often hear in conversations between Florentines; it means that without money you can’t do anything.
So, did you know any of them?!
