The language arose as a result of the mixing of two cultures in the years after Omu Hẽwã -186X (equivalent to around 1500 B.C. in Earth terms, or 3,500 years ago). Until OH -186X, the islands were the sole preserve of two groups of the Yelé people.
Proto-Maritime is reconstructed as having 22 phonemes. It was characterised by its three points of vowel articulation, a lack of voicing contrast amongst consonants and the prominence of velar, uvular and pharyngeal sounds. Syllables were simple or moderately complex.
The standard model of PM phonology has stood the test of time, but some uncertainties remain. These are indicated below. The language was unwritten. It is believed that there were two dialects, one spoken on Mohai, one on Peku. Little is known about them, however.
