The Nahali Alphabet

Nahali and Kalto (also spelled Nihali) are two names for the same language (or very closely related speech), sharing the ISO 639-3 code nlx. This is directly analogous to the relationship between Gawar-Bati and Narsati on this site — two names for the same Dardic language of Chitral.

In linguistic literature, "Nihali" is often preferred by typologists and language documentation researchers. "Kalto" appears in certain community and administrative contexts. "Nahali" reflects yet another naming convention. All names refer to the same endangered language isolate of Nimar district, Madhya Pradesh. The existence of multiple names reflects the community's multilingual context and the different scholarly and community perspectives on naming the language.

Nahali (ISO 639-3: nlx), also known as Nihali or Kalto, is an endangered language spoken by a small community in Nimar district, Madhya Pradesh, India, near the Maharashtra border. The speakers live in villages along the Tapti (Tapi) river plains — a region of contact between Madhya Pradesh and Maharashtra communities speaking Marathi, Hindi, and Korku.

Estimates of Nahali speakers range from a few hundred to a few thousand, reflecting both the small community size and varying methodologies of linguistic surveys. Most speakers are bilingual or multilingual in Marathi and/or Hindi, which are the dominant languages of education and administration in the region.

A language isolate is a language with no demonstrable genealogical relationship to any other known language family. Famous examples include Basque in Europe and Burushaski in Pakistan. Nahali (Nihali/Kalto) is considered a language isolate or near-isolate of South Asia, meaning it does not clearly belong to the Indo-Aryan, Dravidian, Austroasiatic, or Tibeto-Burman families that dominate India.

Some proposals have suggested ancient Austroasiatic (Munda) connections for Nahali, based on certain lexical similarities. However, these remain unproven hypotheses. Nahali's status as a potential isolate makes it extraordinarily valuable for understanding the prehistoric linguistic landscape of central India before the expansion of Indo-Aryan and Dravidian languages.

Nahali is written in Devanagari script (Unicode Block U+0900–U+097F) — the same script used for Standard Hindi, Marathi, Nepali, and Sanskrit. Devanagari is a Brahmic abugida, written left to right, in which each consonant letter carries an inherent /a/ vowel that is modified or suppressed by diacritical marks called matras.

The Devanagari alphabet for Nahali includes 33 consonants, 11 independent vowels, a set of vowel diacritics (matras), and native Devanagari digits (०–९). Since Nahali uses the same script as Hindi and Marathi, written Nahali is visually identical to these languages — though the spoken language is entirely distinct as a potential language isolate with no known relatives.

Yes. Nahali is classified as endangered by the Endangered Languages Project. The speaker community in Nimar district, Madhya Pradesh is small and embedded in a multilingual environment dominated by Marathi and Hindi. The language lacks formal educational support, a standardised literary tradition, or significant documentation compared to better-studied Indian languages.

Most Nahali speakers are bilingual or multilingual, and younger generations show a tendency to shift toward Marathi and Hindi for everyday communication. As a potential language isolate, Nahali cannot be reconstructed from related languages if lost — making its documentation and revitalisation uniquely urgent among South Asian endangered languages.

Nahali is a language isolate — it does not belong to any established language family. The surrounding languages belong to the Indo-Aryan family (Hindi, Marathi, Bhili) and the Austroasiatic family (Korku, a Munda language of Madhya Pradesh), but Nahali shows no systematic genealogical affinity to either group.

Historical-linguistic proposals suggesting Austroasiatic connections for Nahali have attracted scholarly interest but have not been accepted as demonstrating genetic kinship. Nahali's isolation means it may preserve features from a prehistoric language stratum of central India — evidence of a linguistic landscape that existed before the major language expansions of the past several millennia.
