What is the meaning of the name Dermot ?

The baby name Dermot is a Male name , 2 syllables long and is pronounced UK: /ˈdɜːrmət/ US: /ˈdɝːmət/ (respelling: DER-mət).

Dermot is Irish in Origin.

Dermot is the Anglicized form of the Old Irish personal name Diarmait (modern Diarmaid/Diarmuid). Etymologists link it to dí “without” plus a root denoting envy or enmity, giving traditional senses like “free from envy” or “without enemy,” sometimes broadened to “a freeman.” The name has deep Gaelic pedigree and generates the hereditary surname Mac Diarmada, Anglicized MacDermot/McDermott.

It was borne by early saints and powerful rulers, notably Diarmait mac Cerbaill, a 6th-century High King of Ireland, and Diarmait Mac Murchada (Dermot MacMurrough), the 12th-century king of Leinster associated with the Norman arrival. Dermot also echoes in legend through Diarmuid Ua Duibhne of the Fenian Cycle. Variants and spellings include Dermod, Diarmaid, Diarmuid, and Diarmait; short forms Derm and Derry occur. Usage remains steady in Ireland and among the diaspora, but is rare elsewhere.
