Computer memory found by an Italian (5)
I believe the answer is:
roman
'an italian' is the definition.
(someone from Rome)
'computer memory found by' is the wordplay.
'computer' becomes 'an' (I can't justify this - if you can you should believe this answer much more).
'memory' becomes 'ROM' (Read-Only Memory on a computer).
'found by' means one lot of letters go next to another.
'an' put after 'rom' is 'ROMAN'.
Can you help me to learn more?
(Other definitions for roman that I've seen before include "Does this citizen live in a manor?" , "ancient empire" , "Denizen of Italian capital" , "Type of candle, nose etc" , "Of an Italian city" .)
