Taken in by a consumer (5)
I believe the answer is:
eaten
'taken in by' is the definition.
(I've seen this before)
'a consumer' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
The remaining letters 'eten' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eaten that I've seen before include "Got" , "Swallowed" , "Put away" , "used for food" , "corroded" .)
