Eg consuming a tin? (6)
I believe the answer is:
eating
This clue might be a double definition.
'eg consuming' is the first definition.
(consuming is a kind of eating)
'a tin?' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
(Other definitions for eating that I've seen before include "Taking in solid food" , "Putting away" , "Ingestion" , "Out to dinner?" , "at breakfast?" .)
