Answer point as appropriate (3)
I believe the answer is:
apt
'appropriate' is the definition.
('apt' can be a synonym of 'appropriate')
'answer point' is the wordplay.
'answer' becomes 'a' (abbreviation eg in Q and A).
'point' becomes 'pt' (**).
'a'+'pt'='APT'
'as' acts as a link.
(Other definitions for apt that I've seen before include "Tap (anag.)" , "may be appropriate" , "Pertinent" , "flat" , "To the point" .)
