Kaus vs Kemeja??

[Guluten]

Kemeja = shirt
Kaus = t-shirt

[brendanzi]

Maybe it's the Jakarta slang in me, but i would say "Saya pakai baju hitam"

[Rick392366]

t-shirt = kaus

What are the differences between ''memakai'' ''pakai'' and ''pake''

[Rick392366]

"pakai" (verb) is the base word.
"memakai" is the base word + "me-" prefix , making it a transitive verb.
The formal way is to use the "me-" prefix.
There is no difference in meaning between these two.

"pake" is how it's often used (pronounced) in daily conversation, but that's not the official spelling.

[HenriCooks]

That makes a lot of sense, terima kasih :)

In Indonesia, I learned "kaos" spelled with an "o"

[Rick392366]

It's often spelled and pronounced like that.
In daily speech it doesn't really matter.
The issue is, the official spelling is "kaus", and not "kaos" (that has another definition).
