This contribution introduces Challow, a previously unreported and undescribed Tibeto-Burman language spoken in the Ukhrul district of Manipur, North-East India. It includes preliminary sociolinguistic, phonological, and lexical information, compared with data from other languages of the region. The study also offers a 100-items Swadesh wordlist of Challow lexical entries. At first glance, Challow reveals interesting properties, such as the presence of an original p(ə̆)-prefix so far unattested in the languages of the area, and typologically rare phonological processes.
