## Definition

things that must happen or be true before something else can happen. You agree on them first, then you do the main thing.

For teachers: requirements or circumstances that must be satisfied before a subsequent event, agreement, or process can proceed. Often appears in the plural when several separate requirements apply together.

## Examples

- We agree on preconditions before we start the project.
- The landlord lists several preconditions for renting the flat, including proof of income and references.
- The ceasefire negotiations stalled because each side attached preconditions that the other viewed as non-negotiable, turning preliminary talks into a debate about the terms of talking itself.
