Forms

causō (present infinitive causāre, perfect active causāvī, supine causātum); first conjugation[1]

Etymology

It is from Latin causa (“cause; lawsuit”) + -ō, an active verb beside the classical deponent causor, which is formed from the same noun.[2][3] The TLL and the MLW treat its forms together with those of the deponent, and the Hungarian medieval dictionary heads them both under one entry.[2][1][4]

Earliest recorded meaning

The TLL's first active example of the sense “to cause” is in Gennadius' work on church doctrine: to believe that foods are evil or cause evils to those who eat them is not Christian.[2][5]

Semantic evolution

Martin of Braga uses the active for bringing a complaint against someone who did harm by force, a sense of the deponent,[2] and Boethius uses the participle causātum for that which is caused.[2]

The sense “to cause” became common in Medieval Latin, above all in scholastic philosophy.[1][6][7] Albertus Magnus uses it of causes and of what arises from them,[1] and the Carmina Burana call on the tongue to sing of causes and of the thing caused.[1] Grosseteste writes that the cause of good is better than what it causes,[6] and Ockham of universal causes from which countless effects are caused.[6] In medicine William of Saliceto writes of worms that cause deafness,[1] and records speak of excesses that cause dangers or of injuries caused to plaintiffs.[6][4] With an infinitive it meant “to cause to be done”: an Oxford record of 1448 complains that fish retailers cause fish to be sold at more than double the price.[6] The active also kept the senses of the deponent, “to allege as a reason, complain, accuse, go to law”.[1][4]
