Open the drapes? (6)
I believe the answer is:
spread
'open' is the definition.
(synonyms)
'drapes?' is the wordplay.
'drapes' can be anagrammed to 'SPREAD'.
But, I'm not clear how the anagram is indicated.
'the' is the link.
Can you help me to learn more?
(Other definitions for spread that I've seen before include "Sort of betting" , "expansion?" , "Distribute or disperse widely" , "Open, fan out, unfold" , "Extend - banquet" .)
