defect

Built-in weakness

A defect is a flaw, imperfection, or shortcoming that diminishes quality or function: a manufacturing defect, a heart defect, defects in the plan.

The verb, stressed on the second syllable, means to abandon allegiance—typically switching sides in war or politics: The diplomat defected to the West.

A defector is someone who has defected.
