No single confirmed literal meaning. Commonly cited candidate derivations include Old English elements meaning roughly 'valley house' and a Scottish Gaelic/Pictish origin (from the village of Dallas, Moray, first recorded in 1226 as 'Dolays Mychel') meaning roughly 'meadow dwelling.' These are competing theories rather than an established etymology, and the city of Dallas, Texas is officially credited by its own historical marker to a personal surname (U.S. Vice President George M. Dallas) rather than to a descriptive word meaning — though even that attribution is contested. The ultimate origin of 'Dallas' is genuinely disputed: it may derive from an Old English or Scottish Gaelic/Pictish place-name element meaning roughly 'valley/meadow dwelling,' or the Texas city (and thus the modern given name) may be named after U.S. Vice President George M. Dallas — but even that attribution is contested among historians, with rival candidates including other members of the Dallas family. No single theory is confirmed.
