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. Raw, juvenile writers imagine that, by pouring forth figures often, they render their compositions warm and animated. Youthfully, Youthfulness.
