I ka is not interchangeable with ma ka?
When do you use "i" and when do you use "ma" for on? I can't seem to get it right.
When do you know to use ke instead of ka
If the next word begins with K, E, A, or O you use Ke. Otherwise use Ka.
Something you put next to your head like a phone does not belong on a place where you sit like a chair
Use i anytime is okay. But ma can be used if something is inside or on top
