He brings out what may be procured (8)
I believe the answer is:
producer
'he brings out' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'may be procured' is the wordplay.
'may' indicates anagramming the letters (I've seen 'might' mean this (I've seen this in other clues)).
'procured' is an anagram of 'PRODUCER'.
'what' is the link.
Can you help me to learn more?
(Other definitions for producer that I've seen before include "Impresario" , "He works on programme" , "Creator; supervisor (of programme, play)" , "Procured (anag.)" , "Zeffirelli perhaps" .)
