I know two languages, Malay and English.
Malay is my native language, growing up in Malaysia. Sadly, though, my Malay isn't as proficient as my English, because throughout my younger years I grew up with English/Western materials. It's pretty rusty to say at least, but it's not as terrible as it is. My only problem with Malay is that I can never articulate my sentences right, and it's common in Malaysia to sometimes mix your sentences with English and Malay, so there's that. The place I grew up with also made me gotten really used to its slang, so I'm not very great in proper Malay.
I am fluent in English, because of what I stated before. My accent when I talk in English seems too Westernized.
I used to study Arabic when I was younger, though I wasn't very interested in learning it. Now being older, I have regretted that situation and I now only know how to count numbers and say yes and no in Arabic. I wish I could speak Arabic today. Oh well.
