Reason one’s seeking carpet dealer’s style? (6)
I believe the answer is:
format
'style?' is the definition.
(I've seen this before)
'reason one's seeking carpet dealer's' is the wordplay.
I cannot quite understand how this works, but
'carpet' could be 'mat' (I've seen this before) and 'mat' is located in the answer.
The remaining letters 'for' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
(Other definitions for format that I've seen before include "Structure, layout" , "Way of presentation" , "Broadsheet or tabloid, say" , "General arrangement of a publication" , "Secure firmly in position" .)
