One corner in heaven that’s just like velvet (5)
I believe the answer is:
silky
'just like velvet' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?
'one corner in heaven' is the wordplay.
'one corner' becomes 'il' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'heaven' becomes 'sky'.
'il' placed inside 'sky' is 'SILKY'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for silky that I've seen before include "With a smooth, gleaming surface" , "seal" .)
