Translation:Are you a translator or an interpreter?
question for native speaker on comma use in this context: in english, "are you a translator or an interpreter" (vs COMMA after translator) implies 3 possibilities: interlocutor is a translator, an interpreter, OR NEITHER. The same sentence WITH a comma (are you a translator, or an interpreter) implies only two possibilities: translator or interpreter, but definitely one of the two. Is romanian the same in that regard?
Very interesting question!... As learned in school, Romanian does NOT allow comma before ”și” (AND in English) and ”sau” (OR in English). In cases as the one you show (ești un traducător sau un interpret?”) a native would have no problem in answering with ”nici una, nici alta” (NEITHER) even if no comma was used. This is of course different from English, where comma has a well understood meaning in such cases. There are though some exceptions, as shown here http://www.ele.ro/social/educatie/tu-pui-virgula-corect-vezi-regulile-pentru-folosirea-virgulei-in-limba-romana-51188 or here http://scri.ro/cand-punem-virgule-9-870.html or even here http://www.scientia.ro/homo-humanus/44-dificultati-ale-limbii-romane/152-reguli-folosire-virgula.html , the most common being when you INTERCALATE an explanation (ești un traducător, ca tatăl tău, sau un interpret?”)
