Mike loathing holding clubs in scrap (7)
I believe the answer is:
modicum
'scrap' is the definition.
(thesaurus)
'mike loathing holding clubs' is the wordplay.
'mike' becomes 'M' (phonetic alphabet: alpha, bravo, charlie etc.).
'loathing' becomes 'odium' (synonyms).
'holding' indicates putting letters inside.
'clubs' becomes 'c' (abbreviation in card games).
'odium' going around 'c' is 'odicum'.
'm'+'odicum'='MODICUM'
'in' is the link.
(Other definitions for modicum that I've seen before include "A small portion" , "suggestion" , "touch" , "A small amount as of drink" , "dash" .)
