It was appropriate to get together (4)
I believe the answer is:
meet
'to get together' is the definition.
('meet' can be a synonym of 'get together')
'it was' is the wordplay.
I cannot really understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
The remaining letters 'mee' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'appropriate' acts as a link.
Can you help me to learn more?
(Other definitions for meet that I've seen before include "Get together socially or for business" , "Fitting to come together" , "Confront" , "Satisfy (requirements)" , "Right and fitting" .)
