Cold and exhausted, go to see (4,2)
I believe the answer is:
call in
'to see' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'cold and exhausted' is the wordplay.
'cold' becomes 'C' (eg on taps).
'and' is a charade indicator (letters next to each other).
'exhausted' becomes 'all in' ('all in' can mean exhausted).
'c'+'allin'='CALL IN'
'go' is the link.
Can you help me to learn more?
(Other definitions for call in that I've seen before include "Drop by" , "Visit" .)
