What does saturate mean?
Saturate is a formal verb meaning to fill something completely, especially with liquid, or to cause something to reach its capacity. It also describes a market becoming supplied with so much of a product that demand is exceeded. The word appears frequently in environmental and scientific writing: saturated soil cannot absorb much more water, while a saturated solution contains the maximum amount of a substance that can dissolve under given conditions. Figuratively, saturation can mean overwhelming exposure, as when an audience is saturated with publicity or a subject is saturated with images. The word suggests fullness and limit rather than merely a moderate amount, and its use often carries a sense of excess or saturation. Although it sounds formal, it remains common in professional and general contexts.

Where does saturate come from?
Saturate comes from the Latin verb saturare, meaning 'to fill full' or 'to sate', which was derived from satur, 'full' or 'sated'. English borrowed the word in the early 17th century for the idea of filling or soaking something completely. Its sense of excessive supply developed through the related English terms satiate and satiety, which continue to reflect the same Latin root.
