... cheers Shakespeare's old habits (7)
I believe the answer is:
tabards
'old habits' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe you can see a link between them that I can't see?
'cheers shakespeare's' is the wordplay.
'cheers' becomes 'ta' (both can informally mean thank you).
'shakespeare's' becomes 'bard's'.
'ta'+'bards'='TABARDS'
Can you help me to learn more?
(Other definitions for tabards that I've seen before include "Sleeveless tunics" , "Heralds' coats" , "Bastard (anag.)" .)
