A person who lives in or comes from Boston, Massachusetts.
From 'Boston' + '-ian' (English suffix forming demonyms—words for people from places). The suffix '-ian' comes from Latin and appears in 'Canadian', 'Venetian', and many other place-based names.
Boston's founding in 1630 and its role as America's intellectual center meant 'Bostonian' became synonymous with intelligence, culture, and sometimes snobbishness—think of famous Bostonian families like the Kennedys.
