Megleno-Romanian is a member of the Italic branch of the Indo-European language family. More specifically, it is an Eastern Romance language, a language formed after the retreat of the Roman Empire from South-Eastern Europe. Some linguists consider it to be an intermediary between Romanian and Aromanian, often being considered either a dialect of Romanian, a dialect of Aromanian, or an independent language. It is much closer to standard Romanian than the Aromanian language, suggesting that it split from Proto-Romanian later than Aromanian. Megleno-Romanian is influenced a lot by South Slavic.
