Diarmaid Ó Muirithe (11 November 1935 – 11 July 2014)[1] was an Irish lexicographer, journalist and author.
Ó Muirithe was born in New Ross, County Wexford, attending Trinity College Dublin and the National University of Ireland, before working as a primary school teacher, a freelance writer, and newsroom journalist at RTÉ.
He later became a senior lecturer in Irish at University College Dublin, as well as a Fulbright Professor of English in the United States, as well as chair of Irish Studies in St Mary's University, Halifax, Canada.
Maurice Manning described Ó Muirithe as "an internationally respected expert on dialect based on his knowledge of English dialect and what has now been recognised as a distinct field of study, Hiberno-English".
[4][5] Poet Séamus Heaney called him a "[k]eeper of Ireland’s word-hoard".
