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]
