Forms

Etymology
It is formed from Latin onus (“load, burden”) + -ō.[2][3][1] De Vaan traces the noun to Proto-Italic *ones- and Proto-Indo-European *h₃en-os (“load”), cognate with Sanskrit अनस् (ánas-, “heavy cart”) and perhaps Hittite anii̯e/a- (“to work, carry out”).[4] Servius explains that ⟨onustus⟩ has no ⟨h⟩ because it comes from ⟨onus⟩.[3]
Earliest recorded meaning
Plautus, prologue to the Menaechmi: onerāvit nāvim magnam multīs mercibus, “he loaded a big ship with many goods”.[2][4]
Semantic evolution
Onerō is to load a ship or animal with freight, to load a person (Virgil's hands loaded with darts), and to heap things up with heavy objects (Lucretius: temples heaped with corpses).[2] From this come weighing down and overloading (Livy: lest heavy baggage burden the column), overwhelming in battle, and filling with food and drink (Sallust: vīnō et epulīs onerātī).[2] Plautus already uses it for loading someone with joy or with abuse; figuratively it is to burden with tasks, debts or legal liabilities, and to make something more burdensome, aggravate.[2][1] Poets also use it for covering.[1]
Church Latin glosses it “burden, load down, overwhelm, oppress”.[5]
