Cast drapes apart (6)
I believe the answer is:
spread
'cast' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'drapes apart' is the wordplay.
'apart' indicates an anagram.
'drapes' with letters rearranged gives 'SPREAD'.
Can you help me to learn more?
(Other definitions for spread that I've seen before include "Land in America" , "advance" , "Scatter - padres (anag)" , "we hope to avoid in middle age" , "Type of betting" .)
