Set aside deed poll avoided by editor (6)
I believe the answer is:
devote
'set aside' is the definition.
(I've seen this in another clue)
'deed poll avoided by editor' is the wordplay.
'poll' becomes 'vote' (I've seen this before).
'avoided by' is a deletion indicator.
'editor' becomes 'ed' (abbreviation).
'deed'+'vote'='deedvote'
'deedvote' with 'ed' taken out is 'DEVOTE'.
(Other definitions for devote that I've seen before include "Give (time or resources to an activity)" , "Set apart" , "Commit" , "Dedicate (oneself)" , "Give wholly to" .)
