Forms

cōnspuō (present infinitive cōnspuere, perfect active cōnspuī, supine cōnspūtum); third conjugation[1]

Etymology

It is from Latin con- + spuō (“to spit”).[2][1][3] The simple verb goes back to Proto-Italic *spū̆-je/o- and Proto-Indo-European *sp(i)uH-ie/o- (“to spit”), an onomatopoeic formation whose beginning, de Vaan notes, was probably reshaped in several languages.[4]

The simple verb is cognate with Ancient Greek πτύω (ptúō, “to spit”), Lithuanian spiáuti and Old English spīwan.[4]

Earliest recorded meaning

Lewis and Short and Georges cite Plautus' Curculio for spitting on someone in contempt.[5][6]

Semantic evolution

It is to spit on someone or spatter them with saliva.[2][5] Lewis and Short find it most often in Petronius, who has a slobbering kiss and spitting on someone in contempt.[5][6] Juvenal uses conspuere sinus, spitting into the fold of one's own garment, which Lewis and Short explain as a charm against the gods' displeasure at proud words,[5] and Apuleius uses it of an epileptic spluttering over someone's face.[5][6]

A line of Furius Bibaculus, Iuppiter hibernas cana nive conspuit Alpes, “Jupiter spits white snow over the wintry Alps”, was quoted by Quintilian as a harsh figure, and Horace parodied it.[5][6] The Vulgate has it several times in Mark and Luke,[7] and Isaiah has a conspuentibus in me, “from those who spat on me”.[5][6] Hilary of Poitiers writes caesum et consputum et crucifixum, “beaten, spat upon and crucified”.[7] Tertullian uses it figuratively for rejecting with contempt, and Cassiodorus of a volcano spewing out.[8]
