The meaning behind Ireland’s name is long, varied and prone to change depending on whom you ask or what history book you read.
Earliest indications suggest it could have been the Norsemen, from Scandinavia, who named it “Inis na Fidbadh” which roughly means “Isle of the Woods” and also referred to Ireland as the “westland isle”.
Other suggestions show Proto-Celts referring to the island as the “Abundant land” whilst the Greeks and Romans called Ireland Ierna and/or Hibernia, the latter of which is still seen in some organisations and groups to this very day!
Éire, and thus Ireland, is said to derive from the old Irish word “Éiru” who was said to be an Irish Goddess and the matron Goddess of the island and sovereignty.
With Ireland’s strong pagan and religious links, throughout the centuries, this connection seems highly likely but a connection, and mashing, of all the names seems even more likely.
