Degradation


Definition:

  • (n.) The state of being reduced in rank, character, or reputation; baseness; moral, physical, or intellectual degeneracy; disgrace; abasement; debasement.
  • (n.) Diminution or reduction of strength, efficacy, or value; degeneration; deterioration.
  • (n.) A gradual wearing down or wasting, as of rocks and banks, by the action of water, frost etc.
  • (n.) The state or condition of a species or group which exhibits degraded forms; degeneration.
  • (n.) Arrest of development, or degeneration of any organ, or of the body as a whole.

Regression


Definition:

  • (n.) The act of passing back or returning; retrogression; retrogradation.

Example Sentences:
