Where does stealth come from?

The first records of stealth come from around 1200. It comes from Middle English stelthe or stelth and is related to the Old English stælthing, meaning “theft.” Stealth used to mean “theft” or the act of stealing, but this usage is now considered obsolete.

In popular culture, stealth is often an important quality for sneaky persons, such as spies, thieves, secret agents, and ninjas. Often, these crafty people have fancy gadgets or technology that allow them to avoid detection and enhance their stealth. In gaming, a character will often have a “stealth skill” to express how good (or bad) they are at sneaking around and avoiding getting found by enemies.

In real life, stealth is equally important for people or things that are trying to avoid being caught. For example, stealth jets and similar aircraft are designed to be difficult to see against the sky or to avoid radar equipment.
