Computerised system for rent revision after midwinter? (8)
I believe the answer is:
internet
'computerised system' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'rent revision after midwinter?' is the wordplay.
'revision' indicates anagramming the letters.
'after' says to put letters next to each other.
'midwinter?' becomes 'inte' (I can't explain this - if you can you should give a lot more credence to this answer).
'rent' with letters rearranged gives 'rnet'.
'rnet' after 'inte' is 'INTERNET'.
'for' is the link.
Can you help me to learn more?
(Other definitions for internet that I've seen before include "What could be offered at some cafes" , "The world-wide web" , "Worldwide computer network" , "Here, blogs" , "World computer network" .)
