Italian Ruby
Also, sometimes, translations have a different (perceived) meaning.A pet peeve of mine is "by default".In Italian it is translated (correctly) "per difetto", and it is "fine" when other people already know the term, but otherways "difetto" is also the translation of "defect", and you will have a tough time explaining to a layman that it is  not a "defect" in that other sense.Another "queer" word (I found it in the Italian version of some database tools) is "ometti" (which is the correct translation of "omit") but that actually I normally read as "little men".In Excel there is "MODE" (statistical function) that is translated into "MODA" which I read as "fashion" and "MOD" (modulo operation) which is translated into "RESTO" (which has a more common meaning of "change" in the sense of what a cashier gives you back when you pay besides that of "remainder").
