Bottom half of damask dyed as requested (5)
I believe the answer is:
asked
'requested' is the definition.
('ask' can be a synonym of 'request')
'bottom half of damask dyed as' is the wordplay.
I cannot really see how this works, but
'as' is within the answer.
The remaining letters 'ked' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for asked that I've seen before include "Enquired; invited" , "Inquired" , "Demanded" , "Requested" , "Questioned" .)
