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 quite 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 present in the answer.
'drink' could be 'cup' (a cup of drink) and 'cup' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
'and' is the 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" .)
