Fair puts a point on blunt end (6)
I believe the answer is:
honest
'fair' is the definition.
(I know that fair can be written as honest)
'a point on blunt end' is the wordplay.
'a point on' becomes 'hone' (I can't explain this - if you can you should give a lot more credence to this answer).
'blunt' becomes 'straight'.
'end' says to hollow out the word (remove centre letters) (I've seen 'ends' mean this).
'straight' with its centre taken out is 'st'.
'hone'+'st'='HONEST'
'puts' is the link.
Can you help me to learn more?
(Other definitions for honest that I've seen before include "Truthful in manner" , "Impartial intermediary" , "Reliable - the son (anag)" , "Not lying" , "Fair and square" .)
