Most cosy and intimate around noon (8)
I believe the answer is:
snuggest
'most cosy' is the definition.
('snug' can be a synonym of 'cosy')
'intimate around noon' is the wordplay.
'intimate' becomes 'snug' (I've seen this before).
'around noon' becomes 'gest' (I can't justify this - if you can you should give a lot more credence to this answer).
'snug'+'gest'='SNUGGEST'
'and' is the link.
Can you help me to learn more?
(Other definitions for snuggest that I've seen before include "Most warm" , "Most welcoming" , "extremely tightly fitting" .)
