Foppish if fee meant disruption (10)
I believe the answer is:
effeminate
'foppish' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'if fee meant disruption' is the wordplay.
'disruption' indicates an anagram.
'if'+'fee'+'meant'='iffeemeant'
'iffeemeant' is an anagram of 'EFFEMINATE'.
Can you help me to learn more?
(Other definitions for effeminate that I've seen before include "(Of a man) like a woman" , "(Of a man) having female characteristics" , "Womanly" , "camp" , "Acting like a woman" .)
