Escape being parted, perhaps? (6)
I believe the answer is:
depart
'escape' is the definition.
(thesaurus)
'parted perhaps?' is the wordplay.
'perhaps?' indicates anagramming the letters (I've seen 'perhaps' mean this).
'parted' anagrammed gives 'DEPART'.
'being' is the link.
(Other definitions for depart that I've seen before include "Quit" , "Leave, vanish" , "make tracks" , "Go away or leave" , "Prated (anag.)" .)
