How cute crush squeezes, becoming friendlier (7)
I believe the answer is:
thawing
'becoming friendlier' is the definition.
I can't tell whether this definition defines the answer.
'how cute crush squeezes' is the wordplay.
'how cute' becomes 'aw' (exclamation).
'crush' becomes 'thing' (I can't justify this - if you can you should give a lot more credence to this answer).
'squeezes' indicates putting letters inside (squeeze can mean hug or embrace).
'aw' inserted within 'thing' is 'THAWING'.
Can you help me to learn more?
(Other definitions for thawing that I've seen before include "Changing from solid to liquid with heat" , "(Of snow) melting" .)
