Waraikú language

Waraikú (Araikú) is an extinct, poorly attested, and unclassified Arawakan language. The only record of this language is in a wordlist published in 1867 by Carl Friedrich Philipp von Martius. Both Kaufman (1994) and Aikhenvald (1999)^[2] leave it unclassified within Northern Arawakan.
