Polished English member pursued by worker (7)
I believe the answer is:
elegant
'polished' is the definition.
(both can mean fancy)
'english member pursued by worker' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'member' becomes 'leg' (member can mean a limb).
'pursued by' says to put letters next to each other.
'worker' becomes 'ant' (worker is a type of ant).
'e'+'leg'+'ant'='ELEGANT'
(Other definitions for elegant that I've seen before include "Ingenious" , "Dignified and graceful" , "Cleverly simple" , "Refined gracefulness" , "Graceful - refined" .)
