Ireland (English)

Where does "Ireland" come from?

The English word 'Ireland' descends from Middle English forms like 'Ireland'[1], which came from Old English 'Īrland'[1]. This Old English term was formed from 'Īras' meaning 'the Irish' and 'land' meaning 'land or country'[2]. The deeper roots trace back to Old Irish 'Ériu'[1], which likely derives from Proto-Celtic '*Φīweriyū'[3] meaning 'earth or soil'[4].

Open questions

The first element in Old English 'Īrland' could alternatively be an unattested singular form '*Īr'. [2]
The vowel sound in Old Irish 'Ériu' is unexpected and unexplained. [3]
