What's the difference between primer and value?

Primer


Definition:

  • (n.) One who, or that which, primes
  • (n.) an instrument or device for priming; esp., a cap, tube, or water containing percussion powder or other compound for igniting a charge of gunpowder.
  • (a.) First; original; primary.

Example Sentences:
