formaltechnical

A shortcoming, imperfection, or fault in an object or design; to abandon one's country or cause in favor of an opposing one.

As a noun, it refers to an inherent flaw, often from manufacturing or design, that prevents something from being perfect or working correctly. As a verb, it means to abandon or desert.

The story behind the word. The word 'defect' comes from the Latin 'deficere', meaning 'to fail', 'to desert', or 'to be wanting'. This Latin root combines 'de-' (away, down) and 'facere' (to do, to make). So, a 'defect' is something that is 'made down' or 'falls away' from what it should be, implying a failure in its making or an absence of what's needed. Its dual meaning as a noun (a flaw) and a verb (to abandon) reflects this sense of falling away from an expected standard or allegiance.

Word relationships
