How do you say is my in Hawaiian?

There isn't a direct translation of "is my" in Hawaiian, as the language structure is different.

To express "is my" you would need to use a phrase depending on the context. Here are a few examples:

"This is my..."

* ʻO ia koʻu... (O ee-a ko-oo-oo...) - This is my...

* ʻO kaʻu... (O ka-oo...) - This is my...

"It is my..."

* ʻO ia koʻu... (O ee-a ko-oo-oo...) - It is my...

* ʻO kaʻu... (O ka-oo...) - It is my...

"Is it mine?"

* ʻO ia koʻu anei? (O ee-a ko-oo-oo ah-nay?) - Is it mine?

"That is mine."

* ʻO ia koʻu. (O ee-a ko-oo-oo) - That is mine.

* ʻO kaʻu kēlā. (O ka-oo keh-lah) - That is mine.

It's important to remember that Hawaiian is a very nuanced language, and the best way to express "is my" will depend on the specific context.
