Retta language

Retta (also called Reta) is a Papuan language spoken on Pura and Ternate islands, located between Pantar and Alor in the Alor archipelago of Indonesia. It is spoken by a few thousand people, and is considered an endangered language by Ethnologue.

It is not related to but not mutually intelligible with Blagar, which is spoken on the north side of Pura Island, and is unrelated to the Austronesian language Alorese, which is spoken on the north side of Ternate. One of its most distinctive features is a morphophonological process where some words can be intensified or made vulgar by replacing an /l/ sound with an [r] sound.
