Head of assembly trick seller? Missing five hundred? (8)
I believe the answer is:
convenor
'head of assembly trick seller? missing' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'five hundred?' is the wordplay.
I cannot really understand how this works, but
'five' could be 'v' (Roman numeral) and 'v' is present in the answer.
'hundred?' could be 'one' (synonyms) and 'one' is found within the leftover letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for convenor that I've seen before include "The member who calls the meetings" , "The one who organises meetings" , "One who gathers poeple for a meeting" , "Chair of meeting" , "One who calls a meeting" .)
