Make most of large tent (6)
I believe the answer is:
marque
'make most of large tent' is the definition.
(I've seen this before)
'most of large tent' is the wordplay.
'most of' means to remove the last letter.
'large tent' becomes 'marquee' (I've seen this before).
'marquee' with its last letter removed is 'MARQUE'.
(Other definitions for marque that I've seen before include "Badge" , "Brand name" , "Brand of car" , "Make most of large tent" , "Make of car" .)
