A saying is any concise expression that is especially memorable because of its meaning or style. Sayings are categorized as follows:

• Aphorism: a general, observational truth; "a pithy expression of wisdom or truth".
  • Adage, proverb, or saw: a widely known or popular aphorism that has gained credibility by long use or tradition.
  • Apothegm: "an edgy, more cynical aphorism; such as, 'Men are generally more careful of the breed of their horses and dogs than of their children.'"
• Axiom: a proposition that commends itself to general acceptance; a well-established or universally conceded principle; a maxim, rule, or law.
• Cliché or bromide: an unoriginal and overused saying.
  • Platitude: a cliché that is unsuccessfully presented as though it were meaningful, original, or effective.
• Epigram: a clever and often poetic written saying that comments on a specific person, idea, or thing; it especially denominates such a saying that is conspicuously put at the beginning of a text.
• Epitaph: a saying in honor of a decedent, often engraved on a headstone or plaque.
• Epithet: a descriptive word or saying already widely associated with a specific person, idea, or thing.
• Idiom, idiomatic phrase or, phraseme: a saying that has only a non-literal interpretation; "an expression whose meaning can't be derived simply by hearing it, such as 'kick the bucket.'"
