Every single participant making finish of a marathon (3,4)
I believe the answer is:
the mall
'finish of a marathon' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'every single participant' is the wordplay.
I cannot quite understand how this works, but
'every' could be 'all' (similar in meaning) and 'all' is found in the answer.
The remaining letters 'them' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'making' acts as a link.
Can you help me to learn more?
(Other definitions for the mall that I've seen before include "Route to Buckingham Palace" , "way in London" .)
