Welmers (1973) and Ladefoged (1971) list Soga [xog], Gwere [gwr], and Kenyi (Kenye) [lke] separately. Kenye and Gwere may be dialects of Soga, Gwere being the most geographically distant. Only Tenga, the major and widely held standard dialect, has development in progress. Lamoogi and Siginyi dialects are largely undescribed and still unwritten. Speakers of Lamoogi and Siginyi consider themselves different ethnic groups, though loosely part of the wider Soga Kingdom. These varieties are all very similar and largely intelligible.
