How is train connected to computer? (2,4)
I believe the answer is:
on line
'to computer?' is the definition.
I can't judge whether this definition defines the answer.
'how is train connected' is the wordplay.
I cannot really see how this works, but
'train' could be 'line' (I've seen this in another clue) and 'line' is present in the answer.
'connected' could be 'on' (synonyms) and 'on' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for on line that I've seen before include "Attached direct to central computer" , "Connected (internet)" , "Available via the internet" , "Connected directly to computer" , "Accessible via the internet" .)
