Depuration

Depuration is a noun that refers to the act or process of freeing something of impurities.  The root word of depuration is the Latin-based word, ‘pure.’ By adding the prefix D-E, meaning ‘completely.’ we get a word that means to make something completely pure. Here’s an example of our word of the day in use: The depuration of our city’s water supply was an important step toward creating better health. Purifying water can be expensive, but it’s worth the cost.
