With a world wide network, we get big-headed (3)
I believe the answer is:
web
'with a world wide network' is the definition.
I can't judge whether this definition defines the answer.
'we get big-headed' is the wordplay.
'get' says to put letters next to each other.
'big-headed' becomes 'b' (this could be a standard abbreviation which I don't know about).
'we'+'b'='WEB'
Can you help me to learn more?
(Other definitions for web that I've seen before include "Network of fine threads" , "The world wide one of the Internet" , "Interwoven structure" , "Network, may be World Wide" , "Lattice" .)
