Pronunciation

  • Classical: [pu.ɛˈriː.lɪs][1]
  • Ecclesiastical: [pu.eˈriː.lis][1]

Forms

puerīlis (neuter puerīle, comparative puerīlior, superlative puerīlissimus, adverb puerīliter); third-declension two-termination adjective[1] The OLD notes the comparative puerīlior in Horace.[2] A spelling with pur- is also recorded.[3]

Etymology

It is from Latin puer (“boy, child”) + -īlis.[2][1][3] De Vaan lists it under ⟨puer⟩, which he derives from Proto-Italic *puwero-, perhaps Proto-Indo-European *ph₂u-ero- (“smaller”); since that form would rather have given ⟨*pawero-⟩, he suggests ⟨puer⟩ may have been built later to the Italic root for “small, young”, or to the stem of pūbēs.[4]

Earliest recorded meaning

De Vaan dates it from Plautus,[4][5] who speaks of reproaching a grown man with “boyish deeds”.[2]

Semantic evolution

It is first “of a boy or child”: Cicero has a boyish look with an old man's wisdom, and aetās puerīlis is childhood.[2][6] The pejorative “childish, immature” starts with Terence, whose character asks why he is being fooled “with your childish notion”.[2] Cicero and later writers use it of silly or trifling things.[2]

Church Latin glosses it “childish”.[7] English puerile (1660s) comes from it or from French puéril; the sense “merely juvenile, immature” is from the 1680s.[8]

Timeline

  • c. 250–184 BC – Plautus of boyish deeds.[2][5]
  • 190–159 BC – Terence in the sense “childish”.[2][5]
  • 81–43 BC – Cicero of boyhood and of childish things.[2][6][5]
