Chew the rag, nominally (6)
I believe the answer is:
gareth
'chew the rag nominally' is the definition.
I can't tell whether this definition defines the answer.
'chew the rag' is the wordplay.
'chew' is an anagram indicator (I've seen 'chewing' mean this).
'the'+'rag'='therag'
'therag' is an anagram of 'GARETH'.
Can you help me to learn more?
(Other definitions for gareth that I've seen before include "M. name; her tag (anag.)" , "Knight of the Round Table -- the rag (anag)" , "- - Edwards (rugby)" , "Man's name" , "K" .)
