Ẹrụwa is an Edoid language of Nigeria.

Phonology

The Ẹrụwa vowel system is hardly reduced from that reconstructed for proto-Edoid. There are nine vowels in two harmonic sets, /i e a o u/ and /ɪ ɛ a ɔ ʊ/.^[3]

The language arguably has no phonemic nasal stops; [m, n] alternate with [b, l], depending on whether the following vowel is oral or nasal. The approximants /ʋ, ɹ, j, w/ also have nasal allophones. The inventory is:^[4]
