Live large with lustful revolutionary (5)
I believe the answer is:
dwell
'live' is the definition.
(to live/dwell somewhere)
'large with lustful revolutionary' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'with' is a charade indicator (letters next to each other).
'lustful' becomes 'lewd' (synonyms).
'revolutionary' says the letters should be written in reverse (letters revolve around).
'lewd' in reverse letter order is 'dwel'.
'l' put after 'dwel' is 'DWELL'.
(Other definitions for dwell that I've seen before include "Inhabit" , "Think moodily (on something)" , "Lodge" , "Reside - linger" , "Focus attention (on)" .)
