Why “jactancy” is a great word
Jactancy is the abstract quality or specific act of boastful self-promotion. From the Latin *jactantia* ('boasting'), from *jactans*, the present participle of *jactare* ('to throw, to boast'), a frequentative of *jacere* ('to throw'). First attested in English in 1623. Unlike 'braggadocio,' which paints a portrait of the loud, hollow boaster, or 'vaunting,' which conjures a heraldic display of triumph, jactancy is the quieter, more pervasive essence of the boast itself. It is the strategic name-dropping in a hushed conversation, the brittle pride clinging to a minor accomplishment, and the subtle inflation of a story over a second drink—the quiet, often sad machinery by which we cast forth a self, hoping the echo will sound larger than the source.
