Look for every employment (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.
Perhaps you can see a link between them that I can't see?
'every employment' is the wordplay.
'every' becomes 'per' ('per' means 'for each' or 'for every').
'employment' becomes 'use' (how something is used).
'per'+'use'='PERUSE'
'for' is the link.
Can you help me to learn more?
(Other definitions for peruse that I've seen before include "Scrutinise" , "Run one's eye over" , "Examine at length" , "Thoroughly examine" , "Read attentively" .)
