Deer ran around as removed (6)
I believe the answer is:
erased
'removed' is the definition.
(to erase is to remove or delete)
'deer ran around as' is the wordplay.
'ran' indicates anagramming the letters (letters have run around).
'around' means one lot of letters goes inside another.
'deer' anagrammed gives 'ered'.
'ered' going around 'as' is 'ERASED'.
(Other definitions for erased that I've seen before include "Rubbed out, deleted" , "torn off" , "Rubbed out, expunged" , "Removed completely" , "Red sea (anag)" .)
