Yngvi,
Yngvin,
Ingwine,
Inguin are names that relate to an older theonym
Ing and which appears to have been the older name for the god
Freyr (originally an
epitheton, meaning "lord").
A torc, the "Ring of Pietroassa", part of a late third- to fourth-century Gothic hoard discovered in Romania, is inscribed in much-damaged runes, one reading of which is gutani [i(ng)]wi[n] hailag ", "to Ingwi of the Goths. Holy".[1]
The Old Norse name Yngvi is a hypocoristic form of an older and rarer Yngvin (OHG Inguin, A-S Ingwine), which is derived from the theonym Ing- and means "worshiper or friend of Ing".[2] The theonym would originally have been Proto-Germanic *Inguz,[3] and it appears in Old Norse Ingvifreyr and Ingunarfreyr, as well as in A-S fréa inguina, and which mean "Lord of the Inguins", i.e. the god Freyr. The name appears also in Ingvaeones which was an alliance of people surrounding a common cult. Other names that retain the theonym are Inguiomerus/Ingemar and Yngling, the name of an old Scandinavian dynasty.[2]
