Effeminate French article left among quite a few (7)
I believe the answer is:
unmanly
'effeminate' is the definition.
(similar in meaning)
'french article left among quite a few' is the wordplay.
'french article' becomes 'un' (indefinite article in French).
'left' becomes 'l' (common abbreviation).
'among' means one lot of letters goes inside another (inserted letters are placed among others).
'quite a few' becomes 'many' (I've seen this in another clue).
'l' going within 'many' is 'manly'.
'un'+'manly'='UNMANLY'
(Other definitions for unmanly that I've seen before include "Not macho or courageous" , "Feeble" , "Not masculine" , "Chicken" , "Effeminate" .)
