Proto-Norse language in the context of "Norse paganism"

Old Norse religion, also known as Norse paganism, is a branch of Germanic religion which developed during the Proto-Norse period, when the North Germanic peoples separated into distinct branches. It was replaced by Christianity and forgotten during the Christianisation of Scandinavia. Scholars reconstruct aspects of North Germanic Religion by historical linguistics, archaeology, toponymy, and records left by North Germanic peoples, such as runic inscriptions in the Younger Futhark, a distinctly North Germanic extension of the runic alphabet. Numerous Old Norse works dated to the 13th-century record Norse mythology, a component of North Germanic religion.

Old Norse religion was polytheistic, entailing a belief in various gods and goddesses. These deities in Norse mythology were divided into two groups, the Æsir and the Vanir, who in some sources were said to have engaged in war until realizing that they were equally powerful. Among the most widespread deities were the gods Odin and Thor. This world was inhabited also by other mythological races, including jötnar, dwarfs, elves, and land-wights. Norse cosmology revolved around a world tree known as Yggdrasil, with various realms, such as Midgard, where humans live. These involved multiple afterlives, several of which were controlled by a particular deity.

North Germanic peoples, Nordic peoples and in a medieval context Norsemen, were a Germanic linguistic group originating from the Scandinavian Peninsula. They are identified by their cultural similarities, common ancestry and common use of the Proto-Norse language from around 200 AD, a language that around 800 AD became the Old Norse language, which in turn later became the North Germanic languages of today.

The North Germanic peoples are thought to have emerged as a distinct people in what is now southern Sweden in the early centuries AD. Several North Germanic tribes are mentioned by classical writers in antiquity, in particular the Swedes, Danes, Geats, Gutes and Rugii. During the subsequent Viking Age, seafaring North Germanic adventurers, commonly referred to as Vikings, raided and settled territories throughout Europe and beyond, founding several important political entities and exploring the North Atlantic as far as North America. Groups that arose from this expansion include the Normans, the Norse–Gaels and the Rus' people. The North Germanic peoples of the Viking Age went by various names among the cultures they encountered, but are generally referred to as Norsemen.

Erilaz or Erilaʀ is a Migration period Proto-Norse word attested on various Elder Futhark inscriptions, which has often been interpreted to mean "magician" or "rune master", i.e., one who is capable of writing runes to magical effect. However, as Mees has shown, the word is an ablaut variant of earl, and is also thought to be linguistically related to the name of the tribe of the Heruli, so it is probably merely an old Germanic military title (see etymology below).

The given name Eric, Erich, Erikk, Erik, Erick, Eirik, or Eiríkur is derived from the Old Norse name Eiríkr [ˈɛiˌriːkz̠] (or Eríkr [ˈeˌriːkz̠] in Old East Norse due to monophthongization).

The first element, ei- may be derived from the older Proto-Norse *aina(z), meaning "one, alone, unique", as in the form Æ∆inrikr explicitly, but it could also be from *aiwa(z) "everlasting, eternity", as in the Gothic form Euric. The second element -ríkr stems either from Proto-Germanic *ríks "king, ruler" (cf. Gothic reiks) or the therefrom derived *ríkijaz "kingly, powerful, rich, prince"; from the common Proto-Indo-European root *h₃rḗǵs. The name is thus usually taken to mean "sole ruler, autocrat" or "eternal ruler, ever powerful". Eric used in the sense of a proper noun meaning "one ruler" may be the origin of Eriksgata, and if so it would have meant "one ruler's journey". The tour was the medieval Swedish king's journey, when newly elected, to seek the acceptance of peripheral provinces.
