Six men are about to question us (9)
I believe the answer is:
examiners
'question us' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how one could define the other.
'six men are about' is the wordplay.
'about' is an anagram indicator.
'six'+'men'+'are'='sixmenare'
'sixmenare' anagrammed gives 'EXAMINERS'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for examiners that I've seen before include "Inspectors" , "Testers" .)
