Polished end of table leg -- walnut -- regularly (7)
I believe the answer is:
elegant
'polished' is the definition.
(thesaurus)
'end of table leg walnut regularly' is the wordplay.
'end of' suggests the final letters.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The last letter of 'table' is 'e'.
The alternate letters of 'walnut' are 'ant'.
'e'+'leg'+'ant'='ELEGANT'
(Other definitions for elegant that I've seen before include "Neat leg? (anag)" , "Modish" , "Polished" , "Dignified and graceful" , "Handsome" .)
