Forms

animōsus (feminine animōsa, neuter animōsum, comparative animōsior, superlative animōsissimus, adverb animōsē); first/second-declension adjective[1]

Etymology

It is from Latin animus (“mind; courage, spirit”) + -ōsus.[2][1][3] De Vaan traces ⟨animus⟩ to Proto-Italic *anamo- (“breath, spirit”) and Proto-Indo-European *h₂enh₁-mo- (“breath”), cognate with Oscan anamúm (“courage, energy; breath”), Old Irish anim (“soul”) and Ancient Greek ἄνεμος (ánemos, “wind”).[4]

Earliest recorded meaning

The OLD's earliest example is the Atellan farce writer Novius, in whom someone promises a strong and spirited man;[2] Varro advises against slaves who are either timid or too spirited.[5]

Semantic evolution

It is “spirited, bold, courageous”, and of actions and attitudes brave: Cicero says we dislike timid gladiators and favour the brave and spirited.[5][2] It could also be “proud, great-souled”, as Ovid's Pyrrhus, proud of his father's image, and “energetic, vigorous”, as Tacitus' lavish corrupter of soldiers.[2] Poets apply it to winds, sea and fire, “boisterous, violent”, as Virgil's East winds that break the woods.[2][5]

In Medieval Latin it described someone of fervent faith.[6]

Word family

Usage notes

Lewis and Short give a separate adjective from anima (“breath, air”), “full of air”, for Ovid's breath-filled throat and the blowing winds, and “full of life”; the OLD treats all these uses under one word from ⟨animus⟩.[5][2]
