Crossword Genius

Annoy an informer (4)

Ross

I believe the answer is:

nark

This clue is a double definition.

'annoy' is the first definition.
(I know that annoy can be written as nark)

'an informer' is the second definition.
(I know that nark is a type of informer)

(Other definitions for nark that I've seen before include "cause irritation" , "Get to" , "upset" , "Stool pigeon" , "Bug" .)
