Large one supplied with carpet that's free (8)
I believe the answer is:
liberate
'free' is the definition.
(I know that free can be written as liberate)
'large one supplied with carpet' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'one' becomes 'i' (Roman numeral).
'supplied with' says to put letters next to each other.
'carpet' becomes 'berate' (I've seen this before).
'l'+'i'+'berate'='LIBERATE'
'that's' is the link.
(Other definitions for liberate that I've seen before include "Set free, emancipate" , "Set free, rescue from bondage" , "Set free, release from slavery" , "Make free" , "Set free, as from oppressive authority" .)
