The cutting edge of food processing (7)
I believe the answer is:
incisor
This clue might be a double definition.
'the cutting edge' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'food processing' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for incisor that I've seen before include "Chisel-edged tooth" , "cutter" , "Canine" , "carnivore requires?" , "Type of tooth" .)
