Choose to imitate what a diner does (5)
I believe the answer is:
chews
'does' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot understand how one could define the other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for chews that I've seen before include "bites" , "Does something with tooth" , "Masticates" , "toffees" .)
