Translation:This is mine.
Fun fact: 'Milik" comes from Arabic ملك /milk/ which means property.
Could "This belongs to me" also be accepted?
I think so.
Shouldn’t “This is my property.” also be accepted? Or “This belongs to me.”
Why not just "ini saya"?
I don't think that works in Indonesian, "ini saya" would typically mean "This is me"
"This mine" definitely doesn't work in English. You need to say "This is mine"
