Tweedy fellow? (6)
I believe the answer is:
harris
'tweedy fellow?' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for harris that I've seen before include "Bomber" , "Hebridean area associated with tweed" , "location off Scottish mainland" , "somewhere in the Hebrides" , "Cloth from Scottish island" .)
