Spy Rebecca moving to online world (10)
I believe the answer is:
cyberspace
'online world' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'spy rebecca moving' is the wordplay.
'moving' indicates anagramming the letters (letters are moved around).
'spy'+'rebecca'='spyrebecca'
'spyrebecca' anagrammed gives 'CYBERSPACE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for cyberspace that I've seen before include "Computerised environment" , "Modern concept" , "Worldwide computer environment" , "Creepy scab (anag.)" , "network that links all" .)
