Purpose, intention (3)
I believe the answer is:
aim
I believe this is a double definition.
'purpose' is the first definition.
(synonyms)
'intention' is the second definition.
(synonyms)
(Other definitions for aim that I've seen before include "Draw a bead on" , "Ambition or goal" , "Point towards a target, or have ambition" , "This is mean" , "road?" .)
