Variation


Definition:

  • (n.) The act of varying; a partial change in the form, position, state, or qualities of a thing; modification; alternation; mutation; diversity; deviation; as, a variation of color in different lights; a variation in size; variation of language.
  • (n.) Extent to which a thing varies; amount of departure from a position or state; amount or rate of change.
