Pay the bill at the chiropodist's? (4)
I believe the answer is:
foot
'pay' is the definition.
(as in footing the bill)
'the bill at the chiropodist's?' is the wordplay.
I cannot quite see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
The remaining letters 'foo' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for foot that I've seen before include "Measure - part of body" , "Infantry - unit of linear measure" , "Distance to the end of a limb?" , "Imperial distance" , "See 24" .)
