Look for every application (6)
I believe the answer is:
peruse
'look' is the definition.
The definition and answer can be both to do with perception as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'every application' is the wordplay.
'every' becomes 'per' ('per' means 'for each' or 'for every').
'application' becomes 'use' (I've seen this in another clue).
'per'+'use'='PERUSE'
'for' is the link.
Can you help me to learn more?
(Other definitions for peruse that I've seen before include "Browse, read casually" , "Read or study carefully" , "Run one's eye over" , "Scrutinise" , "Thoroughly examine" .)
