SUFIX *-ĒN- V SLOVANSKÝCH ETNONYMÁCH VO SVETLE ICH VARIANTNOSTI.

When researching Slavic tribal names, we may come across several tribes with two names based on one and the same root. This concerns, inter alia, also ethnonym Slav/Slavon. The names with the suffix -jane/-ěne, from Proto-Slavic *-ēn-, coexist with the other names, which are mostly autodenomination, and patronymic ones, however, they are not always derived from the latter names and they cannot mostly refer to a place. The assumption of analogies to Moravian-type ethnonyms, which were the most common in medieval times, is not fully justified, since the age of the records suggests that the records with the suffix *-ēnare as old or in several cases even older than those without it (e.g. *Tuchorěne, known as early as the 10th century, is recorded as *Tuchori only in the second half of the 11th century). In the light of this fact, the suffix *-ēn- must be reinterpreted. [ABSTRACT FROM AUTHOR]
