Turing to protect information is after computing language (7)
I believe the answer is:
italian
'language' is the definition.
(Italian is a language)
'turing to protect information is after computing' is the wordplay.
'turing' becomes 'alan' (I am not sure about this - if you are sure you should believe this answer much more).
'to protect' indicates putting letters inside (inserted letters are held or protected).
'information' becomes 'i' (common abbreviation for information).
'is after' is a charade indicator (letters next to each other).
'computing' becomes 'it' (IT is an abbreviation for Information Technology).
'alan' enclosing 'i' is 'alian'.
'alian' after 'it' is 'ITALIAN'.
Can you help me to learn more?
(Other definitions for italian that I've seen before include "Native of Genoa" , "A Latin I turn up in Tuscany, say" , "Romance language" , "being in Europe" , "Nationality of benito or Giuseppe" .)
