Made the fellow change the decor (6)
I believe the answer is:
forced
'made' is the definition.
(forcing is a kind of making)
'fellow change the decor' is the wordplay.
'fellow' becomes 'f' (abbreviation - of a society etc.).
'change' indicates anagramming the letters.
'decor' is an anagram of 'orced'.
'f'+'orced'='FORCED'
'the' acts as a link.
(Other definitions for forced that I've seen before include "Compelled, made to do something" , "Not spontaneous" , "Strained, unnatural" , "Compelled or strained" , "Not natural" .)
