Graceful member admitted by eastern worker (7)
I believe the answer is:
elegant
'graceful' is the definition.
(similar in meaning)
'member admitted by eastern worker' is the wordplay.
'member' becomes 'leg' (member can mean a limb).
'admitted by' is an insertion indicator.
'eastern' becomes 'e'.
'worker' becomes 'ant' (worker is a type of ant).
'e'+'ant'='eant'
'leg' inserted into 'eant' is 'ELEGANT'.
(Other definitions for elegant that I've seen before include "Teen gal (anag.)" , "Chic; smart" , "Polished" , "Well-turned" , "A gentle way to be stylish" .)
