Skill in sport mainly raised local business connections (8)
I believe the answer is:
intranet
'sport mainly raised local business connections' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'skill in' is the wordplay.
I cannot really understand how this works, but
'in' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for intranet that I've seen before include "Private comms network" , "Private comms system" , "Private electronic network" , "Private communications network" , "Company computer system" .)
