I understand what you meant! but truth be told, the speakers of Bahasa Indonesia / Malaysia will find alot of cognates to other languages, i've know of a few words in Indonesia/Malaysia that comes directly from Portuguese, Mandarin, Japanese, Russian, German, English, Italian, Indian (Sanskrit), Arabic, and so many others.

I think it's hard to learn the language because one is basically learning a miscellany of all the language in the word.

I did have the honor to speak with @mammasitta during steemfest though, a Vienna-born, her Indonesian is immpecable! so it's definitely possible to learn any language given enough time, even the hard ones.
