Encourage internet company with passion about Net primarily (7)
I believe the answer is:
inspire
'encourage' is the definition.
(inspiring is a kind of encouraging)
'internet company with passion about net primarily' is the wordplay.
'internet company' becomes 'ISP' (internet service provider).
'with' means one lot of letters go next to another.
'passion' becomes 'ire' (ire is passionate anger).
'about' indicates putting letters inside.
'primarily' says to take the initial letters.
The initial letter of 'net' is 'n'.
'isp'+'ire'='ispire'
'ispire' enclosing 'n' is 'INSPIRE'.
(Other definitions for inspire that I've seen before include "Fill with ideas, enthusiasm" , "Stimulate person to adventurous thought or deed" , "Give (feeling of) creativity to" , "Give rise to; breath in" , "Galvanize" .)
