Arosi

Arosi is a Southeast Solomonic language spoken on Makira, formerly called San Cristobal, the easternmost large island of the Solomon Islands, chiefly by communities west of the Wango River. It first entered European records in 1588, when Álvaro de Mendaña's Spanish expedition reached and named the island, though the visitors wrote down only six words.

Its nouns carry no gender marking and divide into simple nouns and phrasal nouns, the latter joined by a preposition expressing possession. Compared with the languages of Malaita, Arosi forms few derived nouns, and counts on a base-ten system in which the word for one thousand is the highest numeral term.
