Part-time board member? (10,5)
I believe the answer is:
occasional table
'part-time board member?' is the definition.
The definition suggests a singular noun which matches the answer.
'board member?' is the wordplay.
I cannot quite see how this works, but
'board' could be 'table' (both can mean food) and 'table' is found within the answer.
The remaining letters 'occasional' 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 occasional table that I've seen before include "Furnishing" , "item of furniture" , "Piece of furniture" .)
