Is there a way to say
if you had come to the meeting... ,
in other words the untrue condition, as opposed to :
if you have come to the meeting... ,
the mere if clause? I used to think it was 假如, but dictionary examples suggest otherwise. For example:
假如有這必要, 就這麼幹吧。
EDIT:
If you use context to express this difference, please provide examples! I would really appreciate an explanation in English (apart from the examples). My Chinese is basic and if I have to translate I only get the basics.
