Wife coming in, nowhere to sit? Don’t worry (2,5)
I believe the answer is:
no sweat
'don't worry' is the definition.
(I've seen this before)
'wife coming in nowhere to sit?' is the wordplay.
I cannot quite understand how this works, but
'wife' could be 'w' and 'w' is located in the answer.
'sit?' could be 'seat' ('seat' can be a synonym of 'sit') and 'seat' is located in the remaining letters.
The remaining letters 'no' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
(Other definitions for no sweat that I've seen before include "easily done" , "OK" , "East won (anag)" , "Not a problem (US colloq.)" , "Don't worry" .)
