Bengali ( ), also known by its endonym Bangla ( ; বাংলা ] ), is an Indo-Aryan language spoken in the Indian Subcontinent.
 It is the national and official language of the People's Republic of Bangladesh, and the official language of some eastern and north-eastern states of the Republic of India, including West Bengal, Tripura, Assam (Barak Valley) and Andaman and Nicobar Islands.
 It is also one of the 22 scheduled languages of India.
 With 205 million speakers, Bengali is the seventh most spoken native language in the world by population.
 Dictionaries from the early 20th century attributed slightly more than half of the Bengali vocabulary to native words (i.e., naturally modified Sanskrit words, corrupted forms of Sanskrit words, and loanwords from non-Indo-European languages), about 30 percent to unmodified Sanskrit words, and the remainder to foreign words.
 Dominant in the last group was Persian, which was also the source of some grammatical forms.
 More recent studies suggest that the use of native and foreign words has been increasing, mainly because of the preference of Bengali speakers for the colloquial style.
 Today, Bengali is the primary language spoken in Bangladesh and the second most widely spoken language in India.

Manang, also called Manangba, Manange, Manang Ke, Nyishang, Nyishangte, and Nyishangba is a Sino-Tibetan language spoken in Nepal.
 Native speakers refer to the language as "ŋyeshaŋ", meaning 'our language'.
 It is one of half a dozen languages in the Tamangic branch of the Sino-Tibetan family.
 Manang and its most closely related languages are often written as TGTM in literature, referring to Tamang, Gurung, Thakali, and Manangba, due to the high degree of similarity in the linguistic characteristics of the languages.
 The language is unwritten and almost solely spoken within the Manang District, leading it to be classified as threatened, with the number of speakers continuing to decline.
 Suspected reasons for the decline include parents not passing down the language to their children, in order to allow for what they see as more advanced communication with other groups of people, and thus gain more opportunities.
 Due to the proximity of the district to Tibet, as well as various globally widespread languages being introduced into the area, use of the native language is declining in favor of new languages, which are perceived to aid in the advancement of the people and region.
