Please get accustomed to being put out! (6)
I believe the answer is:
doused
'being put out' is the definition.
(I've seen this in another clue)
'please get accustomed' is the wordplay.
'please' becomes 'do' (I've seen this in other clues).
'get' means one lot of letters go next to another.
'accustomed' becomes 'used' (I've seen this in another clue).
'do'+'used'='DOUSED'
'to' acts as a link.
(Other definitions for doused that I've seen before include "Extinguished, threw water over" , "Drenched, soaked" , "put out" , "Extinguished or soaked" , "Drenched with liquid" .)
