I take tea, say, and finish off the fangs (8)
I believe the answer is:
eyeteeth
'fangs' is the definition.
(I know this)
'i take tea say and finish off the' is the wordplay.
I cannot quite understand how this works, but
'i' could be 'eye' (I've seen this in other clues) and 'eye' is located in the answer.
'tea' could be 't' (I've seen this in other clues) and 't' is found in the answer.
an anagram of 'the' is 'eth' which is within the answer.
A single letter 'e' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eyeteeth that I've seen before include "Canines in upper jaw, under the optics" , "they're sharp" , "choppers" , "Four pointed structures in the mouth" , "Organs of sight in the mouth?" .)
