Drapes made to open out (6)
I believe the answer is:
spread
'open out' is the definition.
'spread' can be an answer for 'open' (synonyms). I'm not sure about the 'out' bit.
'drapes made' is the wordplay.
'made' indicates anagramming the letters.
'drapes' is an anagram of 'SPREAD'.
'to' is the link.
Can you help me to learn more?
(Other definitions for spread that I've seen before include "Courses" , "Stew or distribute over an area" , "Parsed (anag.)" , "Scatter - padres (anag)" , "extended" .)
