Strip joint on street (6)
I believe the answer is:
divest
'strip' is the definition.
(I know that strip can be written as divest)
'joint on street' is the wordplay.
'joint' becomes 'dive' (I've seen this before).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'street' becomes 'st' (abbreviation).
'dive'+'st'='DIVEST'
(Other definitions for divest that I've seen before include "Strip (someone of clothing)" , "Take off, say clothing" , "Relieve (oneself of garment)" , "Deprive, strip" , "disrobe" .)
