A consuming interest? (6)
I believe the answer is:
eating
This clue might be a double definition.
'a consuming' is the first definition.
(I know that consuming can be written as eating)
'interest?' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for eating that I've seen before include "Taking in solid food" , "Out to dinner?" , "Having supper?" , "Consuming food" , "Ingestion" .)
