Italian city good for British computer pioneer (6)
I believe the answer is:
turing
'computer pioneer' is the definition.
(Alan Turing, 1912-1954)
'italian city good' is the wordplay.
'italian city' becomes 'turin' (Turin is a city in Italy).
'good' becomes 'g' (abbreviation).
'turin'+'g'='TURING'
'for british' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for turing that I've seen before include "Alan --, twentieth century English mathematician" , "British mathematician" , "Alan -, British computer pioneer" , "With his machine, he broke German codes during World War II" .)
