Support revised lease (5)
I believe the answer is:
easel
'support' is the definition.
(easel is a kind of support)
'revised lease' is the wordplay.
'revised' indicates anagramming the letters.
'lease' with letters rearranged gives 'EASEL'.
(Other definitions for easel that I've seen before include "board support" , "artist's requisite" , "Artist's prop" , "The rest of artists" , "artistic aid" .)
