What does osinilshatin mean?

i believe it means where you belong. i know very little spokane but that is the language of the song. here are the lyrics in english.

Who are you when you turn your back?

Where do you go when you leave here?

You can't hide from your truth

Can't run from where you belong

Some things you can't choose

Sometimes you can't have it all

I know your dreams remind you

Where you belong

Memories hold you tight

When there's no comfort in white arms

Loneliness will bring you back

Where you belong
