Allow some deletions (3)
I believe the answer is:
let
'allow' is the definition.
(I know that allow can be written as let)
'some deletions' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'LET' is hidden in the letters of 'deletions'.
(Other definitions for let that I've seen before include "inefficient service" , "Allowed or rented out" , "Umpire's decision" , "Allow; permit" , "hired" .)
