orbō (present infinitive orbāre, perfect active orbāvī, supine orbātum); first conjugation[1]
Etymology
It is from Latin orbus (“bereaved, orphaned”) + -ō.[2][1] De Vaan traces orbus to Proto-Italic *orfo- (“heir, orphan”) and Proto-Indo-European *h₃orbʰ-o- (“turning, what is turned over”), which came to mean inheritance or heir.[3] He cites Weiss's view that the root meant to pass from one social class to another.[3] Cognate with Old Irish orb (“heir; inheritance”) and Ancient Greek ὀρφανός (orphanós, “orphaned”).[3]
Earliest recorded meaning
De Vaan dates the verb from Pacuvius.[3] The TLL cites from Pacuvius the short perfect form ⟨orbasti⟩.[4][5] The OLD's earliest quotation in the general sense is from an unnamed tragedy: a character says that a father robbed him of the light.[2]
Semantic evolution
The verb means to bereave someone of a relative by death: Cicero writes of a mother bereaved of her son.[2][6] Used without an ablative it is to leave desolate, usually to make childless, and an African inscription has death taking a relative away.[2] More widely it is to rob someone of anything precious.[2][1] Lewis & Short give prīvō and viduō as synonyms.[6]
