What's the difference between invariable and unchangeable?

Invariable


Definition:

  • (a.) Not given to variation or change; unalterable; unchangeable; always uniform.
  • (n.) An invariable quantity; a constant.

  • (8) An obsessional artist who was an enemy of all institutions, cinematic as well as social, and whose principal theme was intolerance, he invariably gets delivered to us today by institutions - most recently the National Film Theatre, which starts a Dreyer retrospective this month - that can't always be counted on to represent him in all his complexity.

  • (17) The relative invariance of the allometric baselines of wing morphology in nature is most easily explained as the result of continuous natural selection around a local optimum of functional design.
  • (18) When the paper had some explaining to do, Kuttner was invariably asked to carry out that task.
  • (19) We found that NS1 cells express correctly sized mRNA for the MHC class II genes A alpha, E alpha and the invariant chain.
  • (20) When we reached our summit, or whatever spot was deemed by my father to be of adequately punishing distance from the car to deserve lunch, Dad would invariably find he had forgotten his Swiss army knife (looking back, I begin to doubt he ever had one) and instead would cut cheese into slices with the edge of his credit card.

Unchangeable


Definition:

Example Sentences:

  • (7) Since the incidence of gastric cancer in our population seems to be unchanged, this may suggest a true increase in proximal gastric tumours.
  • (8) When AMT administration was discontinued 40 hrs before precipitation of withdrawal the withdrawal pattern occurred with unchanged intensity.
  • (9) Since then the intensive development of anti-malaria campaigns in urban areas over about ten years led temporarily to a considerable decrease in the level of endemicity, while in rural areas it remained unchanged.
