Trendy English member meeting worker becomes crude (9)
I believe the answer is:
inelegant
'crude' is the definition.
(thesaurus)
'trendy english member meeting worker' is the wordplay.
'trendy' becomes 'in'.
'english' becomes 'e' (abbreviation).
'member' becomes 'leg' (I've seen this before**).
'meeting' is a charade indicator (letters next to each other).
'worker' becomes 'ant' (worker is a type of ant).
'in'+'e'+'leg'+'ant'='INELEGANT'
'becomes' is the link.
(Other definitions for inelegant that I've seen before include "clumsy" , "Unpolished" , "laboured" , "Ungraceful" , "Ugly" .)
