APOPHTHEGM (from the ), a short and pointed utterance. The usual spelling up to Johnson's day was apothegm, which Webster and Worcester still prefer; it indicates the pronunciation - i.e. "apothem" - better than the other, which, however, is more usual in England and follows the derivation. Such sententious remarks as "Knowledge is Power" are apophthegms. They become "proverbs" by age and acceptance. Plutarch made a famous collection in his Apophthegmata Laconica.
