Just take a look at how poorly the bot does for Spanish: https://news.ycombinator.com/item?id=35155577
Like, who on Earth, if learning a language (and not just needing a phrasebook) would ever want to remember foreign language words by rhyming them with a different language?
While truly etymologically related words make sense - such as "escribir" and "scribe", connecting unrelated words is IMHO a bad idea that would do more harm than good.
I currently try learn some Spanish and I had some trouble with Spanish "mirar" accidentally being close enough to Japanese "見る" (which absolutely aren't related, of course, just happen sound similar), so now and then my brain had farted ("hey, I'm speaking in a third language, other than my native and English!") and I could blurt out "miro!" instead of "mira!" or some similarly weird shit unintentionally mixing up two different grammar systems as my brain struggles to explain itself through the grammar I know about. Maybe it's just me, but I think unrelated rhymes and false cognates are a big no-no when learning a new language.
When I've asked ChatGPT (GPT-3.5) to explain me Spanish grammar, such as "explain me 'a' in the beginning of 'a tu hermano le gusta...') it did a decent job explaining me how it works. Factually it matched what I found later, cross-checking.
