Prefer to accommodate Liberal character (7)
I believe the answer is:
flavour
'character' is the definition.
(both can mean a quality or style)
'prefer to accommodate liberal' is the wordplay.
'prefer' becomes 'favour' (synonyms).
'to accommodate' indicates putting letters inside.
'liberal' becomes 'l' (abbreviation).
'favour' enclosing 'l' is 'FLAVOUR'.
(Other definitions for flavour that I've seen before include "Relish" , "essential quality" , "property" , "Season" , "Characteristic quality of something" .)
