Warmly cozy (8)
I believe the answer is:
intimate
'warmly cozy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for intimate that I've seen before include "Sharing a close and affectionate friendship" , "Give hint to close friend?" , "Make known" , "Hint to a familiar friend" , "Thick" .)
