Augmentation is the act or process of augmenting something—adding to it in a way that makes it bigger or better.

This can involve literally or figuratively increasing it in size, number, shape, value, or quality or in some other way.

The augmentation of a material involves the addition of another material or substance to make it stronger. The augmentation of a museum collection involves the addition of new artifacts.

Augment and augmentation are also used in a much more specific way in the context of music, but their general senses are much more commonly used.

Where does augmentation come from?

The first records of the word augmentation come from the 1400s. The verb augment is first recorded earlier and comes from the Late Latin augmentum, meaning “an increase,” from the verb aug(ēre), “to increase.”

Augmentation is often used in the context of an increase in size or amount, but it can refer to other kinds of changes, such as in quality. Augment and augmentation are typically used in a neutral or positive way—they usually imply that whatever is being added to will be made better by the addition.
