The way people eat (6)
I believe the answer is:
course
'the way' is the definition.
(course is a kind of way)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for course that I've seen before include "Routine progress" , "Source (anag.)" , "Mode, of action say" , "Curriculum" , "Flow" .)
