game
The Italian word 'gioco' means 'game' in English. It is used in similar contexts as in English, such as for board games, video games, or sports games. For example, 'gioco da tavolo' means 'board game', 'gioco di calcio' means 'soccer game', and 'gioco dell'oca' is a specific Italian board game called 'Game of the Goose'.
My favourite game is soccer.
In this example, 'gioco' refers to a type of game or sport. 'Mio' is Italian for 'my', 'preferito' for 'favorite, and 'calcio' for 'soccer'.
After the game, we go to eat pizza.
In this sentence, 'gioco' translates to 'game'. The context implies that there's a specific event such as a sports match. 'Dopo' means 'after', 'andiamo' is 'we go', 'a mangiare' is 'to eat', and 'la pizza' is 'pizza'.
This is not a game, it's a serious situation.
In this context, 'gioco' translates to 'game', but it's used here to convey a metaphorical meaning. 'Questo' is 'this', 'non è' is 'is not', 'una situazione' is 'a situation', and 'seria' is 'serious'. The sentence as a whole implies that the situation should not be taken lightly.
