Etymology: Dwyer is a surname, and its story begins in Irish naming practice rather than in a dictionary of common English. It is a shortened English spelling of the Irish "Ó Duibhidhir", meaning "descendant of Duibhuidhir." That personal name is built from two elements: "dubh", meaning black or dark, and "odhar", meaning sallow or tawny. Irish surnames of this kind were formed by prefixing "Ó" (grandson or descendant) to an ancestor's first name, so the family took its identity from a forefather rather than from a place or trade. The name then changed shape as it moved into English-language records. The Irish form contained more syllables and sounds that English speakers and clerks did not easily write, so it was reduced and respelled into the compact form now seen across the English-speaking world. Families with the name are therefore found in many nations, each carrying a version of a single Gaelic description of a dark-haired or sallow-complexioned ancestor.
