One supports standing near person — I lead (10)
I believe the answer is:
misericord
'one supports standing' is the definition.
The definition suggests a singular noun which matches the answer.
'near person i lead' is the wordplay.
I cannot quite understand how this works, but
'person' could be 'miser' (miser is a kind of person) and 'miser' is found in the answer.
'i' is present in the answer.
The remaining letters 'cord' 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 misericord that I've seen before include "Ledge under choir stall seat" , "Part of seat" , "monk's room" , "support for prayer" , "Support for stander in church" .)
