What is the meaning of the name Diarmuid ?

The baby name Diarmuid is a Male name , 2 syllables long and is pronounced DEER-mid (Irish approx. /ˈdʲiəɾmʲɪdʲ/).

Diarmuid is Irish in Origin.

Diarmuid is the modern Irish form of Old Irish Diarmait/Diarmaid, a Gaelic masculine name meaning “free from envy” or “without enemy,” from the prefix dí- “without” plus a root associated with jealousy or enmity. It appears throughout early medieval annals borne by kings and churchmen, notably Diarmait mac Cerbaill, and in legend as Diarmuid Ua Duibhne, the tragic lover of Gráinne in the Fenian Cycle, cementing its romantic-heroic aura.

Variants include Diarmaid (standard in Irish), Diarmad/Diarmid (Scottish Gaelic), and anglicized Dermot, Dermott, and Dermod; Darby and even Jeremiah/Jeremy sometimes served as English stand-ins in colonial records, though they are unrelated etymologically. The surname Mac Diarmada survives as MacDermot/McDermott. The name remains well used in Ireland and among the diaspora, appreciated for its deep Gaelic roots and the appealing sense of magnanimity implied by its meaning.
