e) The Slavs and the placenames of Rumania
Placenames of Slavic origin
Slavs were living in the territory of present day Rumania from the 6th century until the 12thB13th centuries. In Byzantine chronicles, the territories north of the lower Danube were, after the 5th century, designated Sclavinia (_klabhnia). The early Slavic migrants found most probably Gepidae, Avars (many Slavic tribes were brought to the territory by the Avars), and possibly Dacians in several places. All these peoples disappeared in the course of time in the masses of the Slavs.
A placename or geographical name based on a Slavic word does not automatically imply a Slavic namegiving. In case the word in question exists (or existed once) in the Rumanian language, the placename or geographical name may have been given by Rumanians.
The number of names of Slavic origin, given by Slavs and borrowed by the Rumanians is very high in the entire country. According to the Slavic language they derive from, these names are divided into four groups: (1) an eastern Slavic (Ukrainian) in the northeast, (2) a small area of western South Slavic in the southwest, (3) an eastern South Slavic (Bulgarian) area in the south (the largest of the Slavic areas), and (4) a northwestern area with special features.
The sound pattern of these names is of a more recent date as compared to the placenames of Slavic origin in Greece. They show:
(1) Metathesis of the groups tart, talt B B|lgrad, Predeal, etc.
(2) The y > i change B Bistra (older form in Slavic: bystr\).
(3) The disappearance of the semi-vowels: Crasna (older form in Slavic: kras\na), Ocna (ok\no).
(4) Slavic corresponds always to Rumanian în, îm.
Since these sound patterns appeared in Slavic in or after the 9th century, the
Slavic placenames and names of rivers and streams in Rumania
cannot have been borrowed by the Rumanian language
earlier than that century. In reality, the borrowings occurred much later B that Slavic always corresponds to Rumanian în, îm indicates that names containing this sound were borrowed EARLIEST during the 12th century (cf. above, p. 100).
Da ponovimo - zbog oblika slovenskih pozajmljenica, odnosno u njima izvršenih glasovnih promena, po ovome autoru one nisu mogle biti u rumunski primljene pre 9. stoleća.
