detect
verb
[ dɪˈtɛkt ]
• discover or identify the presence or existence of.
• "cancer may soon be detected in its earliest stages"
Origin:
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’; hence the current (partly influenced by detective).
