Eir is a proper noun used as a name or title, pronounced like a long “ee” sound with a trailing rhotic: /iːr/. It’s a monosyllabic, vowel-focused word that often serves as a personal or fictional designation. In usage, it can denote a character, deity, or brand name, with emphasis on clarity of the vowel and a smooth, unobtrusive “r” ending.
