Diffuser


Definition:

  • (n.) One who, or that which, diffuses.

Infusion


Definition:

  • (v. t.) The act of infusing, pouring in, or instilling; instillation; as, the infusion of good principles into the mind; the infusion of ardor or zeal.
  • (v. t.) That which is infused; suggestion; inspiration.
  • (v. t.) The act of plunging or dipping into a fluid; immersion.
  • (v. t.) The act or process of steeping or soaking any substance in water in order to extract its virtues.
  • (v. t.) The liquid extract obtained by this process.

Example Sentences:
