Etymology and History
Ó Riain is a Gaelic Irish surname, best known in its Anglicized form Ryan. The name is a patronymic, meaning it denotes descent from an ancestor. The prefix Ó (also written as such or anglicized as O') indicates "grandson" or "descendant" in Irish. So, Ó Riain literally means "descendant of Rian." The name Rian is of uncertain origin. It may derive from the Old Irish word rí, meaning "king," possibly with a diminutive suffix, giving the meaning "little king." Some scholars have suggested a link to the word rían, meaning "water" or "ocean," but Professor John Ryan of University College Dublin has discounted these theories due to lack of linguistic evidence. Another related form is Ó Maoilriain, anglicized as Mulryan or O'Mulryan, meaning "descendant of the follower of Rian." The English spelling "Ryan" became dominant over time, with many bearers of the surname shortening Ó Riain or merely adopting the English form.
