Kaytetye (also spelt Kaititj, Gaididj, Kaiditj, Kaytej) is an Australian Aboriginal language primarily spoken in the Northern Territory north of Alice Springs[3] by the Kaytetye people, who live around Barrow Creek and Tennant Creek.

It belongs to the Arandic subgroup of the Pama-Nyungan languages and is related to Alyawarra, which is one of the Upper Arrernte dialects.

[7] Two-vowel systems are unusual, but occur in closely related Arrernte as well as in some Northwest Caucasian languages.

There is a dyadic suffix as well:[6] Dual and plural pronouns distinguish clusivity as well as moiety (or 'section') and generation.

This results in twelve pronouns for 'we':[6] That is, root ay-, dual suffix -la or plural -na, exclusive infix ⟨en⟩, an irregular nasal for even generation, and a suffix for same moiety -ke or opposite moiety -nthe.
