Irish

Middle English Irisce (12th c.), from Old English Īras (“Irishmen”), from Old Norse Írar, from Old Irish Ériu (modern Irish Éire (“Ireland”)), further origin heavily debated but probably from Proto-Celtic *Īwerjū (“fat land, fertile”), from Proto-Indo-European *pi-wer- (“fertile”), from *peyH- (literally “fat”), akin to Ancient Greek πίειρα (píeira, “fertile land”), Sanskrit पीवरी (pīvarī, “fat”).
