More About Substitute

What does substitute mean?

A substitute is someone or something that takes the place of another person or thing. As a verb, to substitute means to make such a switch.

Substitute is used in a variety of contexts, but it is perhaps most commonly associated with substitute teachers and players in team sports who replace a player in the game. In both cases, the word is often shortened as sub.

Example: Mr. Jones was sick today so we had a substitute.

Where does substitute come from?

The first records of substitute come from the 1300s. It comes from the Latin word substitūtus, from the verb substituere, meaning “to put in place of.”

Substitute teachers replace the regular teacher when they are unable to teach, typically because they are sick. A substitute usually only serves in that role for a day or two, but there are also long-term substitutes who replace a teacher for longer periods of time, such as when they’re on maternity leave.

In sports, a substitute is a player who replaces a player who is currently playing. This can be done for a number of reasons. In soccer (football), substitutes are often used late in a game to replace players who are tired. In basketball, subs are used throughout the game to give players a break. Substitute players are often said to come from the bench, which is a way of referring to the place where players sit when they are not playing, as well as a way to refer to the substitute players collectively.

Substitute is used in many other contexts as both a noun and a verb. In grammar, substitute is used as a noun to refer to a word that serves as a particular kind of replacement. In chemistry, to substitute is to replace one or more elements or groups in a molecule. People often refer to artificial sweeteners as sugar substitutes.

Substitute is synonymous with replacement, and it can appear in phrases and expressions that discuss replacing things, as in There is no substitute for hard work.
