Team backed working for inventor (6)
I believe the answer is:
edison
'for inventor' is the definition.
(Edison is an example)
'team backed working' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'backed' says the letters should be written backwards.
'working' becomes 'on' (on can mean working or activated).
'side' backwards is 'edis'.
'edis'+'on'='EDISON'
(Other definitions for edison that I've seen before include "US inventor of over 1,000 devices" , "scientist" , "Thomas Alva ......, great American inventor" , "No side to this american inventor" , "US scientist/inventor" .)
