Aklanon (Akeanon) is spoken in the province of Aklan on the island of Panay in the Philippines. Its unique feature among other Visayan languages is the close-mid back unrounded vowel [ɤ] occurring as part of diphthongs and traditionally written with the letter E such as in the name Akeanon (Aklanon). However, this phoneme is also present in sister Philippine languages, namely Itbayat, Isneg, Manobo, Samal and Sagada.
