Origin of adenoid

Late 19th century borrowing from French adénoïde, from New Latin adenoīdēs, from Ancient Greek ᾰ̓δενοειδής (ădenoeidḗs, “glandular”), from ᾰ̓δήν (ădḗn, “gland”) + -ο- (-o-) + -ειδής (-eidḗs, “-oid, -like”); equivalent to aden- + -oid. The noun is derived from ellipsis of tumeur adénoïde (“glandular tumor”).
