One or two fatheaded points (3)
I believe the answer is:
few
'one or two' is the definition.
I can't tell whether this defines the answer.
'fatheaded points' is the wordplay.
'fatheaded' becomes 'f' (this might be a standard abbreviation which I don't know about).
'points' becomes 'ew' (east and west, two compass points).
'f'+'ew'='FEW'
Can you help me to learn more?
(Other definitions for few that I've seen before include "Not many, just a handful" , "Indefinite small amount" , "Considerable number, ironically" , "Indefinite but small number" , "Relatively small number" .)
