secern

Learned borrowing from Latin sēcernere, the present active infinitive of sēcernō (“to put apart, divide, separate, sever, sunder; (figuratively) to disjoin, dissociate, part; to discern, distinguish; to exclude, pull aside, set aside, reject”), from sē- (prefix meaning ‘apart; aside; away’) + cernō (“to divide, separate; to distinguish, sift; to perceive, see; to comprehend, discern, regard, understand; to decide”) (ultimately from Proto-Indo-European *krey- (“to divide, separate, sift”)).[1][2]

Senses 1.3 and 2.2 (“synonym of secrete”) derive from the use of the Latin word sēcernere to translate Ancient Greek ἀποκρίνειν (apokrínein), the active infinitive participle of ἀποκρίνω (apokrínō, “to set apart, separate; to choose; to reject on inquiry; to answer, reply”).[1]
