Time to be sort of cosy? (3)
I believe the answer is:
tea
'cosy?' is the definition.
(synonyms)
'time to be sort' is the wordplay.
'time' becomes 't' (abbreviation).
'to be sort' becomes 'ea' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
't'+'ea'='TEA'
'of' is the link.
Can you help me to learn more?
(Other definitions for tea that I've seen before include "For Japanese ceremony" , "Plant" , "Meal/drink" , "Earl Grey?" , "Cha" .)
