French and Portuguese form of Edgar, from Old English ead (rich) + gar (spear).
Edgard is the French and Portuguese adaptation of Edgar, one of the great Old English compound names built from "ead" (wealth, fortune) and "gar" (spear) — a name that once signaled the ideal of a prosperously armed nobleman. Edgar was borne by King Edgar the Peaceful of England in the tenth century, widely considered one of Anglo-Saxon England's most successful rulers, who presided over a unified and stable kingdom. The French spelling Edgard gained lasting cultural prestige through Edgard Varèse, the radical French-American composer whose early twentieth-century works — Amériques, Ionisation, Poème électronique — essentially invented electronic and musique concrète traditions.
That single bearer gave the Edgard spelling an avant-garde, intellectual patina distinct from the plainer Edgar. In Brazil and the Portuguese-speaking world, Edgard remains a dignified, classic choice, far more common than in Anglophone countries. The name also carries literary echoes through Edgar Allan Poe, and through the loyal Edgar in King Lear — one of Shakespeare's most morally steadfast characters, a figure of disguise, endurance, and ultimate vindication.
Whether spelled Edgar or Edgard, the name has a long track record of being borne by men of serious artistic and intellectual ambition. The French variant adds a small continental flourish that parents seeking something just slightly unexpected will appreciate.
