## Definition

to take the place of something older and replace it. You use it when a new rule, version, or agreement replaces an old one.

For teachers: to replace something older with something newer that takes over its place or authority. Often used for laws, rules, versions, and agreements.

## Examples

- The new law supersedes the old rule.
- The updated employee handbook supersedes all previous versions starting next month.
- Although the 2019 agreement still shapes daily practice, the revised treaty signed last spring supersedes it in all matters of trade and border control.

## Synonyms

replace, displace, override, supplant

## Pitfalls

- Not "supercede" but "supersede" — The verb ends in '-sede', not '-cede', despite the /siːd/ pronunciation.

## Usage notes

- The verb is transitive and takes a direct object.
