Modern combination of Anna ('grace') and Beth ('house of God'), both from Hebrew.
Annabeth is a blended name, combining Anna or Anne with Beth, and therefore joining two of the most enduring female naming traditions in the English-speaking world. Anna and Anne come from the Hebrew Hannah, meaning "grace" or "favor," while Beth can stand on its own as a shortened form of Elizabeth, from the Hebrew Elisheva, often interpreted as "God is my oath." The result is a compound name that feels recognizably traditional in its parts but distinctly modern in its full form, a hallmark of many twentieth-century English-language combination names.
Though Annabeth does not have the ancient pedigree of Anna or Elizabeth separately, it has gained cultural visibility through literature, most famously Annabeth Chase in Rick Riordan's Percy Jackson series. That character gave the name a sharpened public image: intelligent, brave, strategic, and self-possessed. Even before that, names of this structure, especially in the American South, fit a broader pattern of double names and fused names such as Marybeth, Annalise, or Sarahbeth, which combine familiarity with individuality.
In usage, Annabeth has evolved from something that might once have sounded regional or homegrown into a name many people perceive as polished and literary. It carries old religious and linguistic roots, but its actual social impression is newer: thoughtful, graceful, and a little storybook-like. Because both elements are so deeply established, the name feels stable despite its relative novelty. Annabeth occupies an interesting middle ground, neither wholly invented nor strictly ancient, and that is part of its charm: it sounds as if it has always existed, even though its rise belongs to more recent naming history.
