Blevins identifies three dialects: Nhanda, the northernmost dialect, Watchandi W13, the central dialect, and Amangu W12, the southern dialect (2001:3). Thus Nhanda is both a language name and a dialect name. There is evidence of initial consonant deletion, a voicing contrast in stops, a distinctive glottal stop, a tripartite systems of bound pronoun, a verbal conjugation contrast between 'unaccusative' and 'unergatives', and an emerging case marking system marking intrasitive subject, transitive subjects and direct objects (Blevins, 2001: 1).

Marmion (2007 p.c.) says that Ngukaja A101 reported by Gratte (PMS 5968, PMS 4878, MS 4134) might be a dialect of Nhanda as well.

Tindale (1974) lists Buluguda W17 and Daguda W15 as group names of Nanda (W14). However, according to Blevins, Buluguda and Daguda are likely local groups of Malgana W18 (2001:2).

However, the identity of both Amangu W12 and Watjanti W14 is somewhat uncertain. The South West Aboriginal Land and Sea Council's Kaartdijin Noongar page lists Amangu as a 'Noongar dialectical group'. Most sources consider Amangu to be related to Nhanda, but Nhanhagardi A93, which is equated with Amangu by several sources (including Blevins), is treated as a dialect of Noongar / Nyungar W41 by Douglas (1976). Douglas also says that, based on his comparison of the data supplied in Curr, Watjanti W13 is clearly closely related to Watjarri A39 (1981).
