Avoid each hidden impression (4)

I believe the answer is:

idea

'impression' is the definition.
(I've seen this in another clue)

'avoid each hidden' is the wordplay.
'hidden' says the answer is hidden in the clue.
'IDEA' can be found hidden inside 'avoid each'.

(Other definitions for idea that I've seen before include "Creative spark" , "Notion, belief" , "It comes to mind" , "Flash of inspiration?" , "Product of the mind" .)

I've seen this clue in The Mirror.
