Protective clothing not right for love (5)
I believe the answer is:
amour
'love' is the definition.
(thesaurus)
'protective clothing not right' is the wordplay.
'protective clothing' becomes 'armour' (I've seen this before).
'not' is a deletion indicator.
'right' becomes 'r' (common abbreviation).
'armour' with 'r' taken away is 'AMOUR'.
'for' is the link.
(Other definitions for amour that I've seen before include "Illicit love" , "Loved one (French)" , "Fling" , "Affaire" , "Sexual liaison" .)
