Drink you initially find nice and warm (6)
I believe the answer is:
toasty
'nice and warm' is the definition.
(I've seen this in another clue)
'drink you initially' is the wordplay.
'drink' becomes 'toast' (toast is a kind of drink).
'you initially' becomes 'y' (I can't justify this - if you can you should give a lot more credence to this answer).
'toast'+'y'='TOASTY'
'find' acts as a link.
Can you help me to learn more?
(Other definitions for toasty that I've seen before include "snack" , "Hot food" , "Pleasantly warm" , "Cosily warm" , "nice and warm?" .)
