Full of spirit, courage, or vigor; characterized by liveliness, energy, or determined will.
From Latin 'animosus' (spirited, courageous), derived from 'animus' (spirit, mind). Rare in modern English but preserved in formal or archaic contexts and in derivative words.
This word is the root of 'animosity'—but isn't it wild that the same Latin root means both 'spirited and courageous' and 'hostile'? Intense emotion can run either direction!
