Forms

morsus m (genitive morsūs); fourth declension[1]

Etymology

It is formed from mordeō (“to bite”) with the noun suffix -tus.[2][3][1] De Vaan takes ⟨mordeō⟩ from Proto-Italic *mordeje-, an iterative present Proto-Indo-European *h₂mord-(e)ye- (“to crush, bite”), cognate with Sanskrit मर्दित (marditá-, “crushed”) and Ancient Greek ἀμέρδω (amérdō, “to deprive of”).[4]

Earliest recorded meaning

Köbler gives Cato as its first author,[5] who prescribes pig dung for the wound if a snake has bitten an ox;[2] Accius has the “viper's bite” whose poison fills the veins.[2]

Semantic evolution

It is a bite, of an animal or of a person eating, as Cicero's ears of grain protected against the bites of small birds, and also the wound made by a bite;[2][6] Statius uses the plural for the jaws.[2][6] From biting it is a grip with the teeth and the grip of a hook or anchor, as Virgil's ships held without the “bite” of the anchor's fluke.[2][1]

It is the corrosive action of a poison, as Cicero's robe of Deianira that tears the flesh, the pungency of food such as cress, and a sharp pain or pang, also of the mind, as Cicero's “the bites of lost liberty are sharper”.[2] Horace uses it of the gnawing of envy.[2] Church Latin glosses it “bite, morsel, biting”, and in medieval Latin it is also a clasp or buckle.[7][8]
