I drink, by the sound of it, and freeze (3,2)
I believe the answer is:
ice up
'freeze' is the definition.
(I've seen this before)
'i drink by the sound of it' is the wordplay.
I cannot really see how this works, but
'i' is found in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found in the answer.
'drink' could be 'cup' (a cup of drink) and 'cup' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for ice up that I've seen before include "become frozen" , "get coat" , "Completely freeze" .)
