adverb词源
late Middle English: from Latin detect- 'uncovered'， from the verb detegere, from de- (expressing reversal) + tegere 'to cover'. The original senses were 'uncover， expose' and 'give someone away'， later 'expose the real or hidden nature of something or someone'; hence the current senses （partly influenced by DETECTIVE）.
