Some basic words in very basic contexts possibly. Things could be much more complicated though if the language she speaks is highly fusional and even basic things like 'hello' are said differently depending on context, or with things like noun cases, in which case even if you know the basic word, you won't understand it in most contexts. There is also the possiblity that words we take for granted don't exist in her language (As an example, I personally know quite a bit of a language in the real world that doesn't even have words for yes or no).
I would just say though that I find it a bit annoying that the MC hasn't even tried to start it seems, which is a lot of missed potential for misunderstandings to add to the comedy.
