Yet he has some standing at meetings (8)
I believe the answer is:
chairman
'yet he has some standing at meetings' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'yet he' is the wordplay.
'yet' becomes 'chair' (I am not sure about this - if you are sure you should believe this answer much more).
'he' becomes 'man' (I've seen this in another clue).
'chair'+'man'='CHAIRMAN'
Can you help me to learn more?
(Other definitions for chairman that I've seen before include "Presiding male at meetings" , "Sedentary male of a committee" , "One in charge of a meeting" , "Boss" , "Committee, club, head" .)
