✕Common Mistakes
Sto divertendo un sacco.
The verb ‘divertire’ is reflexive when you talk about your own enjoyment; you need the pronoun ‘mi’.
Mi sto divertendo un sacco di divertimento.
‘Un sacco’ works as an intensifier after the verb, not as a noun phrase here.
Mi diverto un sacco.
In formal contexts you’d use the simple present ‘mi diverto’ instead of the progressive.

Mi sto divertendo tantissimo.
I’m having a ton of fun.
Sto passando un momento divertente.
I’m having an enjoyable time.
Cultural Tip
‘Un sacco’ is a very common colloquial intensifier among younger Italians and in everyday speech. It adds a friendly, upbeat tone but should be avoided in formal writing or when speaking to authority figures, where a more neutral adverb like ‘molto’ is preferred.
