Etymology and origin of the Latin word subtraho

Confidence
Established
Formation
Derivation
First attested
234–149 BC, Cato
Ultimate origin
Proto-Italic (*traχe/o-)

Pronunciation

  • Classical: [ˈsʊp.tra.(ɦ)oː][1]
  • Ecclesiastical: [ˈsub.tra.o][1]

Forms

subtrahō (present infinitive subtrahere, perfect active subtrāxī, supine subtractum); third conjugation[1] It is also spelled supt-.[2]

Etymology

It is formed from sub- (“under, from below”) and trahō (“to draw, drag”).[2][3] De Vaan traces ⟨trahō⟩ to Proto-Italic *traχe/o-, with its closest cognates in Celtic, such as Old Irish tráig (“ebb, beach”).[4]

Earliest recorded meaning

Cato tells the farmer always to draw off the dregs and lees from the vats, in the De agri cultura.[2]

Semantic evolution

It is to draw from under, as in Cato, to undermine, as Caesar's Gauls drawing away the siege ramp with tunnels, to haul up a sail, and in medicine to draw off morbid matter.[2][3] It is to take something away so that others lose it, to withdraw food or drink, as Cicero's horse-tamers who withhold food, and to withdraw one's eyes, as Tacitus' Nero who ordered crimes but did not watch them.[2][3][1] It is to withdraw a person from his companions or from sight, to detach troops, and reflexively to keep away from an activity, as Cicero's “the more gladly I withdraw from the senate house”.[2][3][1] It is to rescue from a danger, as Livy's man who escaped disgrace and punishment by suicide, and to take away something abstract, as Cicero's “words have no footing if you take away the matter”.[2][3]

Church Latin glosses it “remove or take by stealth, escape”.[5]
