In the late 16th century, scientists noticed that the loose masses separated from a solution or suspension through precipitation often resembled tufts of wool, and they began to refer to them as flocks, using a word for "tufts" that comes ultimately from the synonymous Latin word floccus. (This flock is not related to the flock that refers to a group of animals, which comes from Old English flocc, meaning "crowd" or "band.") About two centuries later, the Late Latin term flocculus found its way into English and was also used with the meaning "a small loosely aggregated mass." By the end of the 19th century, a whole word family had been formed, including the adjective flocculent, the noun floccule, and the verb flocculate.
