Be about to get ahead with something in person (4)
I believe the answer is:
bone
'something in person' is the definition.
I can't tell whether this defines the answer.
'be about to get ahead' is the wordplay.
'be about' means one lot of letters goes inside another.
'to get' becomes 'be' ('get' can mean 'come to be').
'ahead' becomes 'on' (synonyms).
'be' placed around 'on' is 'BONE'.
'with' is the link.
Can you help me to learn more?
(Other definitions for bone that I've seen before include "#Close to it is risque" , "Part of skeleton" , "Skeleton substance" , "See 6" , "It makes up the skeleton" .)
