Loving fat fee with action settled? (12)
I believe the answer is:
affectionate
'loving' is the definition.
(similar in meaning)
'fat fee with action settled?' is the wordplay.
'with' says to put letters next to each other.
'settled?' indicates an anagram.
'fat'+'fee'='fatfee'
'fatfee' put after 'action' is 'actionfatfee'.
'actionfatfee' anagrammed gives 'AFFECTIONATE'.
(Other definitions for affectionate that I've seen before include "Tender" , "Displaying fondness" , "Fond" , "friendly" , "Showing fondness" .)
