Word Origin and History for blowhard

also blow-hard, 1840, a sailor's word (from 1790 as a nickname for a sailor), perhaps not originally primarily meaning "braggart;" from blow (v.1) + hard (adv.). An adjective sense of "boastful" appeared c.1855, and may be a separate formation leading to a modified noun use.
