"Socially... the Baale class themselves with their Southeast Surmic neighbors - Chai-Trima - under the ethnonym Suri... This strong cultural bond has also been strengthened by frequent intermarriage between these groups, also resulting in compound bilingualism... The sociolinguistic situation among the Baale has, therefore, been characterized as 'bilingualism with diglossia', where most Baale speak Chai-Trima as a second language, but the latter do not tend to speak Baale... [Baale] speakers have exhibited resistance to total assimilation. Resistance has been so strong that their language has been preserved, and in effect, the Baale maintain a double identity. The Baale case... represents an instance of contact-induced language change resulting in rapid horizontal assimilation towards the neighboring but genetically related language."
