Trendy surveyor with implanted lead for instance and gold in tooth (7)
I believe the answer is:
incisor
'tooth' is the definition.
(incisor is a kind of tooth)
'trendy surveyor with implanted lead for instance and gold' is the wordplay.
I cannot quite see how this works, but
'trendy' could be 'in' ('in' can mean fashionable) and 'in' is located in the answer.
'gold' could be 'or' ('or' is the heraldic name for gold) and 'or' is found within the answer.
The remaining letters 'cis' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for incisor that I've seen before include "Front tooth" , "Canine" , "Ivory perhaps" , "One takes a bite" , "companion could be Goofy" .)
