## Definition

describing a space where the air pressure is kept higher than the air outside. This is common in planes so you can breathe normally at high altitudes.

For teachers: maintained at a constant atmospheric pressure higher than the surrounding environment. Often used predicatively after 'is' or 'remains', or attributively before nouns like 'cabin' or 'suit'.

## Examples

- The airplane cabin is pressurized for the passengers' comfort.
- Astronauts must wear a pressurized suit to survive the vacuum of space during their mission.
- Maintaining a pressurized environment within the deep-sea laboratory is essential for the safety of the researchers and the integrity of their delicate equipment.

## Pitfalls

- Not "the cabin is pressure" but "the cabin is pressurized" — Learners often use the noun 'pressure' when the adjective 'pressurized' is required to describe the state of a container.

## Usage notes

- Often functions as a participial adjective; typically precedes the noun it modifies or follows a linking verb.
