Older Romanian etymological dictionaries tended to assume a borrowing in many cases, usually from a Slavic language or from Hungarian, but etymological analysis may show that, in many cases, the direction of borrowing was from Romanian to the neighboring languages. The current "Dicţionar explicativ" (the DEX) published by the Romanian Academy continues to list many words as borrowings, though the work of other linguists (Sorin Olteanu, Sorin Paliga, Ivan Duridanov, "et al.") may indicate that a number of these are in fact indigenous, from local Indo-European languages.
