Leerish (natively lheere [ˈɬəɦəɾə]) is an experimental language, created in 2015 by Aryo Nazaradeh, based on the idea of having only one vowel. The language was first introduced in its proto stage by Nazaradeh on /r/conlangs under the username /u/the-postminimalist, on June 4th, 2015. Leerish is an SOV, head-final language with the use of postpositions. Its vocabulary is heavily based on Iranian languages, such as Persian, Balochi, and Avestan. Other words are entirely artificial, like yee (IPA [ˈjəɦə]; English: to be).
