Mack

Derived from the Gaelic patronymic element mac, meaning 'son of', the word migrated from Scottish and Irish surnames into American English as both a given name and a familiar term of address. It entered the national register in 1880 as an independent name rather than a formal abbreviation. Over forty-three thousand boys have received it since recordkeeping began.

The name lands with the sudden weight of a dropped wrench. Most listeners associate it with heavy diesel freight or a midcentury mechanic with his sleeves rolled to the elbow. The reality is split: about thirty percent of living bearers belong to Generation Alpha, while another twenty-six percent are baby boomers. It reads like a surname that refused to spend time on extra syllables.
