What's the difference between essentially and virtually?

Essentially


Definition:

Example Sentences:

  • (18) Of 55 new open reading frames analysed by gene disruption, three are essential genes; of 42 non-essential genes that were tested, 14 show some discernible effect on phenotype and the remaining 28 have no overt function.
  • (19) Essential characteristics of the composite bone cement included a homogeneous and uniform fiber distribution, and a minimal increase in apparent viscosity of the polymerizing cement.

Virtually


Definition:

  • (adv.) In a virtual manner; in efficacy or effect only, and not actually; to all intents and purposes; practically.

Example Sentences:

  • (1) Virtually every developed country has some form of property tax, so the idea that valuing residential property is uniquely difficult, or that it would be widely evaded, is nonsense.

  • (5) Thin films (OD approximately 0.7) of glucose-embedded membranes, prepared as a control, showed virtually 100% conversion to the M state, and stacks of such thin film specimens gave very similar x-ray diffraction patterns in the bR568 and the M412 state in most experiments.
  • (6) The pathway of ketogenesis in renal cortex must differ from that of the liver, as beta-hydroxy-beta-methylglutaryl-CoA synthetase is virtually absent from the kidney.
  • (7) The diet increased the formation of a cholesterol-rich very low density lipoprotein (VLDL), decreased high density lipoprotein (HDL)-associated cholesterol and phospholipids, but had virtually no effect on low density lipoprotein (LDL)-lipids.
