Cease to be a consumer (6)
I believe the answer is:
starve
'cease' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how they can define each other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for starve that I've seen before include "Suffer from lack of food" , "Suffer great hunger" , "Die from lack of food" , "Suffer extreme hunger" , "Vaster (anag)" .)
