What the man with the concealed weapon was wearing? (7)
I believe the answer is:
garment
'wearing?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'what the man with the concealed weapon' is the wordplay.
I cannot quite see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'man' could be 'gar' and 'gar' is located in the answer.
The remaining letters 'men' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'was' acts as a link.
Can you help me to learn more?
(Other definitions for garment that I've seen before include "Grant me (anag.)" , "An article of clothing (7)" , "Piece of clothing" , "Item of clothing" , "Maybe a jacket" .)
