Annoying people breaking ranks? (5)
I believe the answer is:
narks
'annoying people' is the definition.
'narks' can be an answer for 'people' (nark is a kind of person). I'm unsure of the 'annoying' bit.
'breaking ranks?' is the wordplay.
'breaking' indicates an anagram.
'ranks' with letters rearranged gives 'NARKS'.
Can you help me to learn more?
(Other definitions for narks that I've seen before include "singers" , "Coppers' ..... are slang police informers" , "Annoys; informers (sl.)" , "Irritates" .)
