Find greeting concerning, but employ them (4)
I believe the answer is:
hire
'find' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'greeting concerning but employ them' is the wordplay.
I cannot really understand how this works, but
'greeting' could be 'hi' (hi is a kind of greeting) and 'hi' is present in the answer.
'concerning' could be 're' (both can mean on a particular topic) and 're' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hire that I've seen before include "Pay to use something" , "Charter, employ" , "Engage; rent" , "Payment for use" , "Rent, employ" .)
