Succeed at the long jump away from home?
I believe the answer is:
outbound
'succeed at the long jump' is the definition.
I can't tell whether this definition defines the answer.
'away from home?' is the wordplay.
'away' becomes 'out' ('out' can be a synonym of 'away').
'from' says to put letters next to each other.
'home?' becomes 'bound' (I can't explain this - if you can you should give a lot more credence to this answer).
'out'+'bound'='OUTBOUND'
Can you help me to learn more?
(Other definitions for outbound that I've seen before include "Headed away from home base" , "Going away" , "Leaving" , "Being in the process of departing" .)
