FAQ
Frequently Asked Questions
It is a real word, though it originated as jargon in the MIT tech culture of the 1950s. It is now found in standard dictionaries and is considered informal/colloquial English.
Yes. While its primary use is digital/technical, it is often used metaphorically for any shoddy, redundant, or poorly constructed physical objects, especially if they are clutter (e.g., 'a drawer full of electronic cruft').
They are closely related. 'Bloat' often refers to software that has become unnecessarily large and slow. 'Cruft' is the specific, often old, redundant, or badly written parts (code, features, hardware) that contribute to that bloat. Cruft is the 'stuff' that causes bloat.
Almost never. It is inherently pejorative, implying uselessness, poor quality, and obstruction. In rare, ironic contexts, someone might affectionately refer to 'lovable cruft' in an old system, but this still acknowledges its problematic nature.
