Sui generis
Sui generis (; ) is a Latin phrase that means "of its (his, her, their) own kind; in a class by itself; unique."
Two-spirit
"Two Spirit" is not interchangeable with "LGBT Native American" or "Gay Indian"; this title differs from most western, mainstream definitions of sexuality and gender identity in that it is not a modern, self-chosen term of personal sexual or gender "identity"; rather, it is a sacred, spiritual and ceremonial role that is recognized and confirmed by the Elders of the Two Spirit's ceremonial community. While some have found the term a useful tool for intertribal organizing, not all Native cultures conceptualize gender or sexuality this way, not all tribes have ceremonial roles for these people, and the tribes who do usually use names in their own languages. While pan-Indian terms are not always appropriate or welcome, the term has generally received more acceptance and use than the term it replaced.
