"I have nine chairs in my room."
Translation:ʻEiwa oʻu noho ma koʻu lumi.
What I read elsewhere is that normally possession comes after the noun, e.g. ʻEkolu paikikala o Keoki "Keoki has three bicycles." But in the case of pronouns, they come before the verb instead, so you get ʻEkolu ona paikikala "He has three bicycles." As to why that happens, I couldn't say.
