Muduga influenced by Kannada [kan], Tamil [tam], Malayalam [mal], and Tulu [tcy], but not a dialect of any of them. Though it has similarities with Tamil in grammatical structure, it cannot be treated as a dialect of Tamil. It is distinct in the Dravidian family (Menon 1996:274 citing Rajendran). No dialects of Muduga determined on survey. Lexical similarity: 55%–57% with Malayalam [mal], 59% with Muthuvan [muv], 60% with Tamil [tam], 75% with the Attapady dialect of Irula [iru], 82%–83% with Attapady Kurumba [pkr].
Vigorous, children learn it first. Home, village, religion. All ages. Positive attitudes. Education plays major role in determining bilingualism, but even some higher educated Muduga are not adequately bilingual in Malayalam [mal].
National census population figures combine Muduga of Attapady with Muthuvan, who, despite the similarity of the spelling of their ethnonym, are entirely different and separated by geographic and cultural distance (Menon 1996). Traditional religion, Hindu.
