Sharp object's point grasped by young servant (4)
I believe the answer is:
fang
'sharp' is the definition.
I know that 'sharp' relates to this answer. I also know that both the answer and definition are singular nouns
'object's point grasped by young servant' is the wordplay.
'object' becomes 'F' (F is an example).
'point' becomes 'n' (North).
'grasped by' means one lot of letters goes inside another (I've seen this in other clues).
'young servant' becomes 'ag' (I can't explain this - if you can you should give a lot more credence to this answer).
'n' put within 'ag' is 'ang'.
'f'+'ang'='FANG'
Can you help me to learn more?
(Other definitions for fang that I've seen before include "Large pointed tooth" , "Long pointed tooth" , "Snake tooth" , "Eye tooth" , "Poisonous tooth" .)
