There's been a proposal on Area51 for a Hebrew Language SE for a while now, but as it isn't open yet, is it appropriate to ask a question about the Hebrew language here?
Hebrew has the same status here as any other language. Questions related to Judaism are on topic, while questions not related to Judaism are not. If your Hebrew/English/Spanish/Russian/Latin/Arabic/etc. question is about something to with Judaism, then it's on topic.
"What does this word in my Jewish text mean?" = On topic.
"What does this word from a billboard mean?" = Off topic.
