Budza or Buja (Embudja, Limbudza) is a Bantu language of the Democratic Republic of the Congo.
There are several neighbouring minor languages which Maho (2009) lists as closely related: C371 Tembo (Litembo or Motembo â distinguish Chitembo/Kitembo), C372 Kunda (Likunda â distinguish Chikunda), C373 Gbuta (Egbuta) and C374 Babale. Only Tembo, with 5,000 speakers, has been assigned a separate ISO code; Glottolog concludes that it and Kunda are a single language, distinct from Budza, Gbuta and Bango.
Budza distinguishes between high tone and low tone.
