There are too many different meanings for passer. Can you recommend some synonyms please?

I suspect that this question has not been answered because there are too many variables. It's a matter of context, context, context (repeated deliberately) and so you would need to be clear about what it is that you want to convey in order to select the most appropriate form of this verb. When you are clear then it would be possible to look for synonyms for that particular context.

Bonjour Robyn !

I understand your confusion, but it's very similar to some English verbs that are used to express many things, such as "to get" (a nightmare for French speakers!).

I can't really give you synonyms as for most of these cases, "passer" is the colloquial verb to use, however I'd be happy to provide alternatives if you give me specific cases :)

Bonne journée !
