The languages she claims to be able to speak:>English, Japanese, Spanish, Korean, Dutch, Swiss German, German
Swiss German and German are essentially the same. Especially at school people are forced to write proper German. It sounds extremely different and some words are different, but no actual skill needed there. (And looking back to the ‘calling my dad’ video, she’s definitely not fluent in German.)
She’s been taught Dutch, Spanish and I guess English (because afaik it’s mandatory) at school. (See description)
If you watch the video, it clearly looks like she’s reading off a computer screen (especially with her leaning forward and squinting) and even then she’s struggling. I’ve had French in school too so I could definitely shit together a paragraph and pronounce words properly. I couldn’t hold up a conversation beyond introducing myself though and I figure it’s same for her with Spanish and Dutch.
So that’s not ‘speaking a language’ in my book.
Can’t say anything about Korean and Japanese but >which she's been learning since VERY young because she's a weeb
Plus, her being in touch with a bunch of Japanese-speaking people doesn’t make it really that much of an achievement. (Also iirc her Japanese has been critized a lot by native speakers in the comments of several videos.)
The only thing I would consider an actual accomplishment is learning to speak Korean. IF she actually speaks it.
