Quarts and quartz are two words that are pronounced in the same way but are spelled differently and have different meanings. They are homophones. We will examine the difference between the definitions for quarts and quartz, where these words came from and some examples of their use in sentences.

Quarts is the plural form of the word quart, which is a unit of volume. A quart is generally a liquid measurement, though, in the United States, it is sometimes used as a dry measurement. A quart is equal to a quarter of a gallon, or two pints. The word quart is derived from the Latin word quarta which means one-fourth of a part.

Quartz is a crystal mineral made up of silica. Quartz may be colorless or have a range of colors from purple to yellow due to the addition of other minerals while the quartz is forming. Quartz is the second most abundant mineral in the Earth’s crust. The word quartz is derived from the German word Quarz meaning rock crystal.
