Final answer:
The Vlachs are part of the Romance language group, which includes languages derived from Latin and found mainly in Southern Europe, such as Romanian, which is closely related to the Vlachs' language.
Step-by-step explanation:
The Vlachs belong to the Romance language group, which is one of the three major Indo-European language groups in Europe. These languages are Latin-derived and found mainly in Southern Europe.
The Romance languages that evolved from Vulgar Latin include widely spoken languages such as Spanish, Portuguese, Italian, French, and Romanian. In the case of the Vlachs, their language is closely related to Romanian,
highlighting its roots in the Romance linguistic family. Geography has played a significant role in the development and preservation of Romance languages, with many of them surviving in isolated areas such as mountains and islands.
