Keep at work (6)
I believe the answer is:
employ
This might be a double definition.
'keep' is the first definition.
The answer and definition can be both related to consumption as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
'work' is the second definition.
(I know that work can be written as employ)
'at' acts as a link.
Can you help me to learn more?
(Other definitions for employ that I've seen before include "Utilise" , "Occupy" , "Take on - recruit" , "Put to use" , "Give paid work to" .)
