Le espressioni idiomatiche
Idioms are the stretch where 'correct Italian' becomes 'sounding Italian'. They are fixed phrases whose meaning cannot be guessed from the words: literally translated, in bocca al lupo is 'in the mouth of the wolf' — but it means 'good luck'. Mastering the most frequent ones lets you understand TV, podcasts, and casual speech, and lets you sound natural rather than textbook-correct. This lesson covers a high-frequency core: well-wishing (in bocca al lupo / crepi il lupo!), excitement (non vedere l'ora), socializing (fare quattro chiacchiere), teasing (prendere in giro), price (costare un occhio della testa), highs and lows of mood (essere alle stelle / avere un diavolo per capello), and a few more. Treat each idiom as a single lexical unit — change one word and you break the spell.
Wishing well: in bocca al lupo / crepi il lupo!
In bocca al lupo! literally 'into the wolf's mouth' is the standard 'good luck!' before an exam, audition, or any test. The traditional reply is Crepi il lupo! = 'May the wolf die!' (often shortened to just Crepi!). Italians consider buona fortuna suspicious — like saying 'Macbeth' in a theatre — so they avoid it before exams. A second stage-related cousin: in culo alla balena! ('in the whale's bottom!') with reply speriamo che non caghi! — vulgar, used among friends. Use in bocca al lupo in any neutral or formal setting; buona fortuna only when the test is already over or for non-superstitious contexts (a job search in general).
Excitement and impatience: non vedere l'ora
Non vedere l'ora di + infinitive = to not be able to wait, to be looking forward to. Literally 'not to see the hour'. Non vedo l'ora di vederti. = I can't wait to see you. Non vedevo l'ora che finisse la lezione. = I couldn't wait for the class to end (followed by che + congiuntivo if there's a different subject). The negation is structural — there is no positive vedere l'ora. A near-synonym is morire dalla voglia di + infinitive, slightly stronger and more colloquial: muoio dalla voglia di un caffè = I'm dying for a coffee.
Socializing and small talk: fare quattro chiacchiere
Fare quattro chiacchiere literally 'to do four chats' = to have a quick chat. The number quattro is fixed and means 'a small amount, a handful' in many idioms: fare quattro passi = to take a (short) walk, mangiare quattro spaghetti = to have a quick bite of pasta. Related: fare due chiacchiere is also heard, with the same meaning. Andiamo a fare quattro chiacchiere al bar. = Let's go have a chat at the cafe. Don't try tre or cinque — only due and quattro work.
Teasing, joking, and getting fooled: prendere in giro
Prendere in giro qualcuno = to tease / pull someone's leg / make fun of someone. Often friendly, sometimes hostile depending on tone. Mi stai prendendo in giro? = Are you kidding me? Non prenderlo in giro, è permaloso. = Don't tease him, he's touchy. The passive is essere preso in giro = to be made fun of / fooled. A close cousin is scherzare (to joke) — but prendere in giro specifically targets a person, while scherzare is general. Stronger: sfottere (more crude, regional) = to mock relentlessly.
Money: costare un occhio della testa
Costare un occhio della testa literally 'to cost an eye of the head' = to cost an arm and a leg. Quel cappotto costa un occhio della testa. = That coat costs a fortune. Variants: costare una fortuna, costare un capitale, costare un patrimonio — interchangeable. The opposite: costare due lire = to cost almost nothing (lit. 'two lire' — pre-euro currency, kept fossilized in idioms). To haggle: fare un buon affare = to get a good deal. To go broke: rimanere al verde = to be flat broke (lit. 'to stay at the green' — origin: medieval candle-base color in auctions).
Mood: alle stelle / un diavolo per capello
Essere alle stelle literally 'to be at the stars' = to be sky-high (mood, prices, popularity). Il suo umore è alle stelle. = His mood is sky-high. I prezzi sono alle stelle. = Prices are through the roof. The opposite: essere a terra ('to be on the ground') = to be down/dejected. Avere un diavolo per capello literally 'to have a devil per hair' = to be in a furious mood, fuming. Stamattina ha un diavolo per capello, lascialo stare. = This morning he's furious, leave him alone. Related: essere nero (to be 'black' = in a black mood), essere su tutte le furie (to be on all the furies = enraged).
