A fabricator, we do declare! (6)
I believe the answer is:
weaver
'a fabricator' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'we do declare' is the wordplay.
'do declare' becomes 'aver' (averring is a kind of declaring).
'we'+'aver'='WEAVER'
Can you help me to learn more?
(Other definitions for weaver that I've seen before include "Bottom was one (MND)" , "Bottom's trade (MND)" , "Maker of baskets" , "A craftsman" , "He makes cloth or fabric" .)
