Isn't Siapa means 'what'?
No, it means "who"
But when we are asking somebody's name we use "siapa" not "apa"
Why it is kamu siapa and siapa itu and not; siapa kuma or itu siapa. They are just vice versa of each other
kamu siapa/siapa kamu would be 'who are you?'
and "siapa itu?" is who is that?
"Itu siapa?" means "it is who?" and not grammatically correct, it's weird to say even in english
Can it be transulated to what is that..?
"apa itu?" Is "what is that?"
Why is it siapa is sometimes at the front but sometimes at the end? Lol.
Just a matter of emphasis I think.
Siapa itu .. what is that..?
No, siapa means who
"who is this?" was not accepted.
