deprecate

DEP-ruh-kayt /ˈdeprɪkeɪt/
verbC1GREGMAT
technical

To officially declare a software feature or API obsolete and discourage its use, though it remains available for a limited time.

Deprecation is a warning phase. The feature still works, but developers are told to stop using it because it will be completely removed in a future update.

The story behind the word. In the 17th century, to deprecate meant to pray that a disaster would be turned away. Over time, it came to mean expressing disapproval of something. In the 1990s, software engineers adopted it to express disapproval of old code that should no longer be used.

Word relationships

  • phase out: Phasing out is a general business term for gradually removing something, while deprecate is the specific technical term for warning developers about obsolete code.

Memory hook

Think of a 'depreciating' asset like a car losing value; a 'deprecated' feature is losing its usefulness and support. Pray against using this old code.

When not to use
