prōiectō (present infinitive prōiectāre, perfect active prōiectāvī, supine prōiectātum); first conjugation[1][2]
Etymology
It is from Latin prōiciō (“to throw forth, cast out”) + -tō, a frequentative verb.[2][1][3] The TLL notes that the intensive or iterative force of the suffix is not apparent in its uses.[3]
Earliest recorded meaning
It first appears in a tragedy of Ennius, where Agamemnon says to his brother: ego prōiector, quod tū peccās; tū dēlinquis, ego arguor?, “I am cast out because you do wrong; you offend, and I am the one accused?”[3][4][5] The sense there is disputed: the OLD takes it as “banish, expel”, Lewis and Short and Georges as “reproach, accuse”, and the TLL as “expose to danger or punishment”.[2][6][4][3]
Semantic evolution
After Ennius it reappears only in Late Latin.[3] Ammianus Marcellinus uses it of an informer who exposed innocent men in aperta perīcula, “to open dangers”.[3][6][4] The Latin version of Oribasius uses it of hellebore roots taken out after a night in a radish, and the Latin version of Justinian's Novels of lavishing money.[3]
