What is "eriu"

In Irish mythology, Ériu (; modern Irish Éire), daughter of Ernmas of the Tuatha Dé Danann, was the eponymous matron goddess of Ireland.

The English name for Ireland comes from the name Ériu and the Germanic ( Old Norse or Old English) word land.

Since Ériu is represented as goddess of Ireland, she is often interpreted as a modern-day personification of Ireland, although since the name "Ériu" is the older Irish form of the word Ireland, her modern name is often modified to "Éire" or "Erin" to suit a modern form.

Ériu is an academic journal of Irish language studies. It was established in 1904 as the journal of the School of Irish Learning in Dublin. When the school was incorporated into the Royal Irish Academy in 1926, the academy continued publication of the journal, in the same format and with the same title. Originally, the journal was published in two parts annually, together making a volume, but parts slipped further apart after Volume III. Articles are written in either Irish or English.
