1. the process of increasing air pressure in an enclosed space, especially in aircraft cabins to maintain breathable conditions at high altitudes
Usage: technical
2. the act of applying pressure to something or putting pressure on someone

Examples

• The airplane’s pressurization system failed during the flight.
• Cabin pressurization is essential for passenger safety at cruising altitude.
• The spacecraft requires careful pressurization before launch.
• Loss of pressurization triggered the oxygen masks to drop.
• The pressurization of the diving bell allowed workers to descend safely.
• Engineers tested the pressurization system multiple times before approval.
