What's the difference between aerate and oxygenate?
Aerate
Definition:
(v. t.) To combine or charge with gas; usually with carbonic acid gas, formerly called fixed air.
(v. t.) To supply or impregnate with common air; as, to aerate soil; to aerate water.
(v. t.) To expose to the chemical action of air; to oxygenate (the blood) by respiration; to arterialize.

Oxygenate
Definition:
(v. t.) To unite, or cause to combine, with oxygen; to treat with oxygen; to oxidize; as, oxygenated water (hydrogen dioxide).
Example Sentences:
