Country in which I do some computing with single line (5)
I believe the answer is:
italy
'country' is the definition.
(I know that Italy is a country)
'i do some computing with single line' is the wordplay.
I cannot really see how this works, but
'i' could be 'a' and 'a' is found within the answer.
'computing' could be 'it' (IT is an abbreviation for Information Technology) and 'it' is present in the answer.
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is found in the answer.
A single letter 'y' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in which' acts as a link.
Can you help me to learn more?
(Other definitions for italy that I've seen before include "Original member of the European Economic Community" , "Land for strange laity" , "where Juventus normally play" , "Problematical (informal)" , "Land for laity, oddly" .)
