Why this word is great
EVINCE — [Verb] To reveal or demonstrate something, especially a quality or feeling, with conclusive clarity. Its etymology is martial and absolute: from Latin ēvincere ("to conquer completely, vanquish, prove conclusively"), from ē- (intensive form of ex-) + vincere ("to conquer"). Unlike 'manifest' (which proclaims itself in overt display) or 'demonstrate' (which performs an act of willed proof), to evince is to have an inner state irresistibly betrayed by its subtle, inevitable traces. It is the slight tremor in a steady hand that evinces suppressed fear, the dog-eared pages and marginalia of a book that evince deep engagement, or the precise, weary care in cleaning tools that evinces a love beyond passion—the quiet, unconquerable testimony of what lies within, a victory not by force but by irrefutable exposure.
