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, OE 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 OE 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]
