I am currently preparing documents for applying for a job within my own country of residence.
The job ad says that knowledge of a foreign language, Russian in this case, would be a plus. The problem is that I do not speak and am not able to understand Russian. Now, I was being told that some people who were hired in the past for the same position were also not able to speak it and even though that was clearly the minority, I was encouraged to apply. My girlfriend is fluent in the language and I strongly believe that I could pick it up over time, however.
My question is: Should I, in the cover letter, specifically mention that my significant other is fluent in Russian and that I would be willing to learn it? Or is it frowned upon to address this issue since personal matters like these usually do not find themselves in cover letters?
