Broadcast in a manner so pointed! (3)
I believe the answer is:
sow
'broadcast' is the definition.
(sowing is a kind of broadcasting)
'manner so pointed' is the wordplay.
I cannot really understand how this works, but
'so' is found in the answer.
A single letter 'w' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'in a' is the link.
Can you help me to learn more?
(Other definitions for sow that I've seen before include "Female bear" , "One who takes care of litter" , "Scatter seed; pig" , "Female pig" , "She lives in 11" .)
