History & Origin

Deo is the Latin dative of Deus, 'to God,' familiar from Deo gratias. As a living given name it is best known as the everyday short form of Deogratias in Rwanda, Burundi and neighbouring countries, where the full name is widely borne. We give both routes honestly rather than folding one into the other (said 'DAY-oh').

It appears only rarely for boys in the U.S. Rare, short, and resonant.

Did you know? Deo is the Latin word behind Deo gratias, 'thanks be to God.' It is also the ordinary short form of Deogratias in Rwanda and Burundi, where that Christian name is common — so the name lives in two very different places at once (said 'DAY-oh').
