Obscene wife, escorted outside (4)
I believe the answer is:
lewd
'obscene' is the definition.
(I've seen this before)
'wife escorted outside' is the wordplay.
'wife' becomes 'w'.
'escorted' becomes 'led'.
'outside' indicates putting letters inside.
'w' going inside 'led' is 'LEWD'.
(Other definitions for lewd that I've seen before include "Bawdy" , "Indecent and vulgar (4)" , "Indecent, licentious" , "Crude, offensive" , "Dirty" .)
