Charge for each favourite to commit? (10)
I believe the answer is:
perpetrate
'commit?' is the definition.
(I know that commit can be written as perpetrate)
'charge for each favourite' is the wordplay.
'charge' becomes 'rate' (rate is a kind of charge).
'for' says to put letters next to each other (I've seen this in other clues).
'each' becomes 'per' ('per' can mean for each).
'favourite' becomes 'pet' (synonyms).
'per'+'pet'='perpet'
'rate' after 'perpet' is 'PERPETRATE'.
'to' acts as a link.
(Other definitions for perpetrate that I've seen before include "perform" , "Commit (crime)" , "Be responsible for" , "Commit (a bad action)" , "Act" .)
