An English word name from Latin infinitas, meaning boundlessness or endlessness.
Infinity is among the boldest of the word names that emerged in English-speaking naming culture, drawn directly from the mathematical and philosophical concept of endlessness. The word itself entered English in the late fourteenth century from Latin 'infinitas,' meaning 'boundlessness,' from 'in-' (not) and 'finis' (end or boundary). In mathematics, the concept was formalized through the work of Georg Cantor in the nineteenth century, who demonstrated that infinities themselves can have different sizes — a discovery so counterintuitive it scandalized contemporaries and reshaped the foundations of modern mathematics.
As a given name, Infinity belongs to a tradition of aspirational and concept names that parents choose to express profound hopes for their children — names like Serenity, Harmony, Destiny, and Eternity, each encoding a wish or a worldview into the very identity of the child. Infinity takes this impulse to its philosophical extreme, invoking boundlessness itself: the idea that this child's potential, love, or spirit knows no limit. It is a name that makes a statement.
Infinity remains genuinely rare, which gives it both an air of daring and a certain vulnerability to skepticism. It sits outside mainstream naming conventions while expressing something deeply human — the desire to name a child after something vast and beautiful. In an era when names like Reign, Soldier, and Story are given by high-profile parents, Infinity feels both of its cultural moment and entirely its own.
