Employ the writer to interrupt beloved residents (8)
I believe the answer is:
housemen
'residents' is the definition.
(both can mean trainee doctors)
'employ the writer to interrupt beloved' is the wordplay.
'employ' becomes 'use' (synonyms).
'the writer' becomes 'me' (the person who is writing these clues).
'to interrupt' means one lot of letters goes inside another.
'beloved' becomes 'hon' (both are terms of endearment).
'use'+'me'='useme'
'useme' placed inside 'hon' is 'HOUSEMEN'.
(Other definitions for housemen that I've seen before include "Doctors" , "Interns" .)
