What is the greatest number of languages you know people to have achieved functional fluency in? I am currently at functional fluency in three, two of which I am often asked if I grew up in TL regions, which I did not. The other of which is my native. A life goal of mine, of sorts, would be to achieve functional fluency in 4, or if possible, 5 languages. However, I'm wondering where even the most enthusiastic linguists meet a ceiling in this regard. While I have met the occasional polyglot that claims to speak 12+ languages, when tested beyond the basic level they usually falter in at least half of them, if not more. I know a good few trilinguals and occasionally encounter people who speak 4 with at least functional fluency, but more than that, not so much. So, I'm asking for the greatest number of languages that \*\*you, personally\*\* know people to have achieved functional fluency in. As an aside, given that I am 23 with functional fluency in three, does five seem like an achievable long-term target?…
