Diarmaid

Diarmaid is a masculine given name in the Irish language with deep roots in legend and history. Its exact etymology is uncertain, though the most common suggestion is that it means "without envy," from Irish dí "without" and airmait "envy." Alternatively, it has been linked to dí and airmit "injunction."

In Irish mythology, Diarmaid is best known as the lover of Gráinne in the tale The Pursuit of Diarmaid and Gráinne, where he elopes with her away from her arranged marriage to the warrior Fionn mac Cumhaill. Diarmaid is described as a handsome, valiant warrior, and his tragic end adds to the name's romantic and heroic connotations. Several ancient Irish kings also bore the name, including the High King Diarmait mac Cerbaill.

Related forms include Diarmuid (used in Irish mythology) and Diarmait (Old Irish). The name has been anglicized as Dermot and Derry, though etymologically unrelated, the English names Jeremiah and Jeremy have been substituted in Irish contexts. A feminine English equivalent sometimes used was Dimity. Scottish Gaelic forms include Diarmad and Dermid. Notable historical bearers include Diarmait Mac Murchada, a 12th-century king of Leinster who is believed to have invited the Normans to Ireland.
