Variant of Adlai, from Hebrew meaning 'God is just' or 'my witness,' with a modern feminine adaptation.
Adalai is a variant of the ancient Hebrew name Adlai, which appears in the Old Testament as the name of a minor biblical figure — the father of Shaphat, one of King David's overseers — and is understood to mean "my witness," "my ornament," or "God is just," drawing on the root edut (testimony, witness). The name was largely dormant in Western culture for centuries, preserved mainly in religious scholarship, until the twentieth century gave it an unexpected political moment.
Adlai Stevenson I served as Vice President of the United States under Grover Cleveland in the 1890s, and his grandson Adlai Stevenson II became one of the most admired statesmen of the mid-twentieth century — twice the Democratic nominee for president against Eisenhower, later ambassador to the United Nations during the Cuban Missile Crisis, known for his eloquence, wit, and moral seriousness. The Stevenson family essentially owned the name in American consciousness for decades, lending it associations of principled liberalism and intellectual elegance. Adalai's softer spelling — substituting the final i for the traditional y and adding the initial a — gives the ancient name a more lyrical, flowing quality, making it feel simultaneously biblical and fashionable.
It sits in the company of names like Adeline, Adalia, and Adaline that have surged in popularity as parents seek names with genuine historical depth and an old-soul quality that feels neither stuffy nor overly common. Adalai carries witness and testimony in its very roots — a name that means something.
