Enamelled cutter (7)
I believe the answer is:
incisor
'cutter' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for incisor that I've seen before include "Narrow-edged tooth" , "Front tooth" , "Type of tooth" , "Chisel-edged tooth" , "Ivory perhaps" .)
