Smoke hides new vampire weapon? (4)
I believe the answer is:
fang
'vampire weapon?' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'smoke hides new' is the wordplay.
'smoke' becomes 'fag' (both can mean a cigarette).
'hides' means one lot of letters goes inside another.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'fag' enclosing 'n' is 'FANG'.
Can you help me to learn more?
(Other definitions for fang that I've seen before include "Animal's sharp tooth" , "Animal tooth" , "Venomous tooth" , "Poisonous tooth" , "Large pointed tooth" .)
