Pronunciation

  • IPA (Classical): [stʊ.diˈoː.sʊs][1]
  • IPA (Ecclesiastical): [stu.diˈɔː.s̬us][1]

Forms

studiōsus (feminine studiōsa, neuter studiōsum, comparative studiōsior, superlative studiōsissimus, adverb studiōsē); first/second-declension adjective[1] Comparative studiōsior, superlative studiōsissimus.[2]

Etymology

It is from Latin studium (“zeal, study”) + -ōsus.[2][1] De Vaan explains studeō as a stative ⟨*stud-ē-⟩ to a root ⟨*(s)tud-⟩ “to thrust”, as in tundō, meaning “to be thrusting”, hence “to strive after”.[3]

Earliest recorded meaning

The OLD's earliest citations are Plautus and Cato, of eagerness.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant actively interested in something, eager, zealous, diligent, as in Cato's studiōsum reī quaerendae “keen on making money” and Cicero; fond of learning, studious, and as a noun a student, especially of literature or rhetoric, as in Ovid; and warmly attached to a person or party, a partisan, as in Cicero.[2][5]

In Ecclesiastical Latin it means eager, zealous, diligent, studious.[6] English studious (mid-14th century) is from it, and it survives as Italian studioso and Spanish estudioso.[7][1]
