Proper partner? (4)
I believe the answer is:
prim
'proper partner?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for prim that I've seen before include "Stiffly correct" , "Formally prudish" , "Proper (type of rose?)" , "Prudishly disapproving" , "Old-maidish" .)
