IPA: /dɪˈfiːtʃər/
KK: /dɪˈfiːtʃər/
The act of causing something to lose its original form or appearance, often resulting in damage or disfigurement.
The artist's work was criticized for its defeature, which altered the original beauty of the sculpture.
Defeature is formed from "de-" (meaning down or away) and "feature" (from Latin "facere", meaning to make or do). The word describes the act of removing or taking away features from something.
Think of 'taking away' ('de-') the 'characteristics' ('feature') of something — that's what defeature means.
