Abstract
The article presents the autochthonouswords (letter B – brânză „cheese”, brâu „belt”, brusture „burdock”, buc „poor quality wool”, bucura „rejoice”, bunget „oak groves”, buză „lip”) from the Daco-Romanian dialects spoken east of the Prut in over 240 localities in the Republic of Moldova and allogeneic environments in Ukraine, Russian Federation, Republic Abkhazia and Kazakhstan, according to the network of linguistic atlases (ALM, ALRR. Bas., ALCC), dialectal texts, dialectal dictionary etc. The application of the linguistic geography method as a method of researching substrate words highlights not only aspects related to the territorial spread and resistance over time of the examined words, but also aspects related to their history and evolution in the given space, semantics and derivation
