Affectionate wife given outfit (4)
I believe the answer is:
warm
'affectionate' is the definition.
(synonyms)
'wife given outfit' is the wordplay.
'wife' becomes 'w' (abbreviation).
'given' means one lot of letters go next to another.
'outfit' becomes 'arm' (I've seen this in another clue).
'w'+'arm'='WARM'
(Other definitions for warm that I've seen before include "Affectionate; quite hot" , "Passionate; ardent" , "Welcoming - getting close!" , "Showing affection" , "Lively" .)
