Pronunciation

  • Classical: [ĩːˈfan.ti.a][1]
  • Ecclesiastical: [iɱˈfan.t͡si.a][1]

Forms

īnfantia f (genitive īnfantiae); first declension[1]

Etymology

It is from Latin īnfāns (“unable to speak; child”) + -ia.[2][3][1] īnfāns is in- (“not”) and the participle of fārī (“to speak”), which de Vaan traces to Proto-Italic *fā- (“to speak”) and Proto-Indo-European *bʰeh₂- (“to speak”).[4][1] Augustine explained that it is so called because a person cannot yet speak.[3]

Earliest recorded meaning

Köbler dates it from the Rhetorica ad Herennium.[5] The OLD's first example is Lucretius' “inability of the tongue”, which drives children to gestures.[2]

Semantic evolution

Its first sense is inability to speak, and in Cicero inability to express oneself, the want of eloquence of one who knows a subject but cannot explain it.[2][6] It then means infancy, strictly the time before one can talk, and childhood in general, as Seneca the Elder's “from infancy”; also childishness, as Seneca reproaches old men with it.[2] Pliny the Elder uses it collectively of young children.[2] Church Latin glosses it infancy, childhood.[7] English infancy (late 14th century) is from Anglo-French and directly from the Latin word.[8]
