From Irish and Scottish Gaelic dall meaning 'blind,' used historically as a personal name and clan element.
Dall comes from Irish and Scottish Gaelic dall, meaning blind, and it has the compact severity of many early Gaelic forms. Historical personal names often carried meanings that no longer feel literal in modern use, and this is one of them.
The name also appears in clan and surname contexts, which gives it a rugged, regional heritage. As a given name, Dall feels stark, brief, and uncommon. Its simplicity is its defining feature, and that simplicity can make it feel archaic, strong, or even austere depending on context.
Because it is so short, it carries an almost emblematic force: a name with little ornament, but a long memory behind it. Dall feels like a fragment of older language preserved in plain sight.
