Interference from snoop gathering a bit of intelligence (5)
I believe the answer is:
noise
'interference' is the definition.
(synonyms)
'snoop gathering a bit of intelligence' is the wordplay.
'snoop' becomes 'nose' (I've seen this in another clue).
'gathering' is an insertion indicator (gather can mean to acquire or bring in).
'a bit of intelligence' becomes 'i' (I can't justify this - if you can you should believe this answer much more).
'nose' placed around 'i' is 'NOISE'.
'from' is the link.
Can you help me to learn more?
(Other definitions for noise that I've seen before include "Unwanted sounds" , "Loud sound; bruit" , "interference" , "Racket, din" , "Rumour" .)
