Questions & Answers about היה לנו כיף במסיבה.
Because Hebrew is not phrasing this as we being the grammatical subject in the same way English does.
Literally, the structure is closer to:
there was fun to us at the party
So:
- היה = there was / it was
- לנו = to us / for us
- כיף = fun
In this kind of sentence, לנו expresses the people experiencing something, and היה often stays in the masculine singular form because it matches the idea of an impersonal there was construction.
So even though the natural English translation is we had fun, the Hebrew grammar is built differently.
לנו means to us or for us.
It is made of:
- ל־ = to / for
- נו = us
In Hebrew, expressions about having something or experiencing something often use ל־ plus a pronoun:
- יש לי זמן = I have time (literally there is time to me)
- היה לנו כיף = we had fun (literally there was fun to us)
So לנו is the part that gives the meaning we in natural English translation.
