Shakespearean weaver in bed (6)
I believe the answer is:
bottom
I believe this clue is a double definition.
'shakespearean weaver' is the first definition.
(I've seen this before)
'bed' is the second definition.
(I've seen this before)
'in' is the link.
(Other definitions for bottom that I've seen before include "Quark's flavour" , "one of Shakespeare's comic characters" , "Shakespearean weaver" , "seat" , "Lowest point - weaver" .)
