- Derivation

- Ultimate origin
- Latin (ops)
Forms
cōpiōsus (feminine cōpiōsa, neuter cōpiōsum, comparative cōpiōsior, superlative cōpiōsissimus, adverb cōpiōsē); first/second-declension adjective[1] Inscriptions and manuscripts also have quopiosa and cup-.[2]
Etymology
It is from Latin cōpia (“abundance”) + -ōsus.[3][1][2] De Vaan lists ⟨cōpia⟩ under ops (“power, wealth”), which he traces to Proto-Italic *opi- and Proto-Indo-European *h₃e/op-(i-) (“ability, force”), cognate with Hittite happina- (“rich”) and Sanskrit अप्नस् (ápnas-, “possession, property”).[4]
Earliest recorded meaning
Köbler's first source is the Rhetorica ad Herennium.[5] Cicero has a woman who was “quite wealthy and well off”.[3]
Semantic evolution
It means “well supplied, rich”, of persons and cities, and of plants “fruitful”;[3] Cicero says the Greeks' language is richer than Latin, and a case can give “wider scope” for argument.[3] In rhetoric it is “eloquent, having a rich command of words”, sometimes with a pejorative hint, as Cicero's wordy man who talked for hours on a general's duties.[3] It is also simply “abundant, plentiful”, as Cicero's large and plentiful inheritance, and of persons “numerous”.[3]
Church Latin glosses it “copious, plentiful, in great numbers”.[6] English copious (mid-14th century) comes from it.[7]
