Forbid a bachelor to have a bit of fun (3)
I believe the answer is:
ban
'forbid' is the definition.
(banning is a kind of forbiding)
'a bachelor to have a bit of fun' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is found within the answer.
'bachelor' could be 'b' (abbreviation e.g. BA=Bachelor of Arts) and 'b' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ban that I've seen before include "Embargo" , "Exile" , "Veto" , "outlaw" , "Bar, prohibition" .)
