Minister split trousers always (8)
I believe the answer is:
reverend
'minister' is the definition.
(I've seen this before)
'split trousers always' is the wordplay.
'split' becomes 'rend' (I've seen this before).
'trousers' indicates putting letters inside (to trouser can mean to contain or hold).
'always' becomes 'ever' (synonyms).
'rend' going around 'ever' is 'REVEREND'.
(Other definitions for reverend that I've seen before include "Priest" , "Priest's title" , "Mother may go after this" , "Vicar's title" , "Title of a Protestant clergyman" .)
