Sinnott is a surname-turned-given name with Anglo-Norman roots long established in Ireland. It traces to a medieval personal name recorded as Sinod or Synod, ultimately from Germanic/Old English elements meaning “victory” (sige/sigi) and “boldness, daring” (noth). The combined sense is “bold in victory” or “victorious courage,” a compact martial meaning characteristic of early medieval naming.

Brought to Ireland with the Anglo-Norman influx of the late 12th century, the name became especially prominent in County Wexford, where families bearing it appear frequently in records. As a first name, Sinnott remains rare but aligns with the modern trend of adopting distinctive surnames as given names, and it can be used for any gender. Established variants and related spellings include Synnott, Synnot, Sinnett, Sennett, Sinnot, and occasionally Sinnatt or Synnett. There is no native Gaelic equivalent, though the name is deeply woven into Irish history and usage. Pronunciation is typically SIN-ət or SIN-ott.
