Etymology

Origin of stagnant

First recorded in 1660–70; from Latin stāgnant-, stem of stāgnāns “forming a pool,” present participle of stāgnāre “to form a pool of standing water, be inundated”; see stagnate

Explanation

There is a tone to the word stagnant that sounds like what it is: lacking movement, stale, and inactive, especially with exaggerated pronunciation, "staaaagnant." Stagnant came into use in the 17th century as a description for water or air that wasn't moving or circulating, like in a scum-covered pond or a closed-off room. Often things that are stagnant also have a smell from sitting too long in one place. Not that this happens to everyone, but sitting in front of a TV playing video games without moving more than the fingers can make a person stagnant, sometimes with an accompanying odor.
