What the surgeon put in your side? (6)
I believe the answer is:
stitch
'side?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'what the surgeon put in your' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'put' could be 'sit' (sitting is a kind of putting) and 'sit' is found in the leftover letters.
The remaining letters 'ch' 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 stitch that I've seen before include "repair" , "Pain for runner" , "Sort of pain" , "''A . . . . . . in time saves nine'' (6)" , "Sharp pain in side of body caused by exercise" .)
