Syn. -- Puerile; juvenile. -- Youthful, Puerile, Juvenile. Puerile is always used in a bad sense, or at least in the sense of what is suitable to a boy only; as, puerile objections, puerile amusements, etc. Juvenile is sometimes taken in a bad sense, as when speaking of youth in contrast with manhood; as, juvenile tricks; a juvenile performance. Youthful is commonly employed in a good sense; as, youthful aspirations; or at least by way of extenuating; as, youthful indiscretions. "Some men, imagining themselves possessed with a divine fury, often fall into toys and trifles, which are only puerilities." Dryden. "Raw, juvenile writers imagine that, by pouring forth figures often, they render their compositions warm and animated."
