"My name is Tini."
Translation:Nama saya Tini.
In Indonesian, both "I" and "my" are translated into "Saya".
So how to differentiate? The difference is in the word order. Example:
Saya Tini -> I am Tini.
In this sentence, 'Saya' functions as "I"
Nama saya Tini -> My name is Tini.
In this sentence, "Saya" functions as "my".
Hope this helps
