Forms
iactāns (genitive iactantis, adverb iactanter); third-declension one-termination adjective[1]
Etymology
Used as an adjective, it is the present participle from Latin iactō (“to throw; to boast”).[2][1][3] That verb is formed from iaciō (“to throw”),[4] which de Vaan traces to Proto-Italic *jak-i- (“to throw”) further back to Indo-European.[5] Cognate with Ancient Greek ἵημι (híēmi, “to send, let go, throw”).[5]
Earliest recorded meaning
Cicero is its first author:[4] in a fragment of his letters it stands beside insolēns and arrogāns.[6][7]
Semantic evolution
Usually it meant boastful in a bad sense, with or without a genitive: Quintilian describes a pompous man full of himself, suī iactāns, as a hawker of eloquence.[6][7] Virgil, Horace and Pliny the Younger use the comparative iactantior, too boastful, and Pliny speaks of boastful and vainglorious letters.[6][8] The Historia Augusta has the superlative of a most ostentatious lover of the common people.[6][8] In a good sense it meant proud or exultant, as in Statius of Rome and in Claudian of a court.[6][2]
Church Latin kept the sense “boastful, vainglorious”,[9] and Old High German glosses render it with words for boasting.[4]
