Minister split trousers continually (8)
I believe the answer is:
reverend
'minister' is the definition.
(I know that minister can be written as reverend)
'split trousers continually' is the wordplay.
'split' becomes 'rend' (rend can mean to split or tear).
'trousers' indicates putting letters inside (trouser can mean to steal or take).
'continually' becomes 'ever' (ever can mean always).
'rend' placed around 'ever' is 'REVEREND'.
(Other definitions for reverend that I've seen before include "(Form of address to) clergyman" , "Mother may go after this" , "Clergyman's title" , "Title of a Protestant clergyman" , "Vicar's title" .)
