The language is attested only through a few word lists. A few words resemble those of neighboring Kariri (and other Macro-Je) and Xukuru languages, but not enough to support a genealogical connection. Kaufman (1994) reports that "not even Greenberg dares classify this language".

Some of the recorded words:

Resemblances with Macro-Jê languages are in kebra 'stone' (Proto-Je *kɛn), kreká 'head' (*krã), koreké 'hand' (*-ĩkra), and poyá 'foot' (*par). Resemblances with Xukuru are kiro- 'fire' (Xukuru kiyo), kringó 'eat' (kringgo 'feed'), sok 'house' (šekh).

Loukotka (1968) gives three words in Tarairiú:^[1]

• agh 'sun'
• kén 'stone'
• ake 'tobacco'
