Local languages of Western Romance with more similarities with the Romanian context (isolated, rural) prove a reach pool of words common with Romanian, to the point that a lot of Romanian words of confirmed Latin origin, as well as words considered to belong to pre-Roman substrate have been recently identified in Neolatin idioms (see Dan Ungureanu recently identified in Neolatinhere idioms) like the Provensal, Romansh, Sardinian, Corsican, and dialects of different Italian and Spanish regions. (For- For example, the aforementioned "cale/path" seems to have an equivalent in Dalmatian, an extinct Romance language, while pitic (midget) considered of Slavic/Greek origin seems extremely common in Romance along with the related pici (small boy, kid) - see here and here. - Ungureanu also mentions words that were considered pre-Latin, and thus possibly of Dacian/Balkan origin, which in fact have non-Latin but still Italian origin, brought in by the same path of Roman conquest as the Latin words.)
This greatly increases the possibility for Latin roots present in Romanian but possibly absent in the other four main Neolatin languages to bemay eventually be identified in regional languages and dialects of Western Romance.
