Forms: 1600s– ethmoid, 1700s ethmoide, 1700s– ethmoïd, 1800s aethmoid (irregular).

Origin: Either (i) a borrowing from Latin. Or (ii) a borrowing from Greek. Etymons: Latin ethmoides; Greek ἠθμοειδής.

Etymology: < (i) post-classical Latin ethmoides (1513 or earlier), or its etymon (ii) Hellenistic Greek ἠθμοειδής like a strainer, perforated < ancient Greek ἠθμός sieve, strainer (see note) + -οειδής -oid suffix. Compare Middle French, French ethmoïde (1560 as adjective, originally in os ethmoïde; 1612 οr earlier as noun).In ethmoid bone n. at sense A. 1 after post-classical Latin os ethmoides (1538 or earlier), Hellenistic Greek ἠθμοειδὲς ὀστοῦν (Galen). Ancient Greek ἠθμός derives < ἠθεῖν to sift, strain (probably < the same Indo-European base as Lithuanian sijoti, Old Church Slavonic sějati to sift + a verbal suffix in -θ-) + -μός, suffix forming nouns.

A. adj.

1. ethmoid bone n. an unpaired, irregularly shaped bone of the human skull which forms part of the orbits and nasal cavity, consisting of a horizontal plate (the cribriform plate) pierced by many small openings for the passage of olfactory nerves, a vertical plate descending from this, and two lateral masses containing air cells; (also) the homologous bone in the skulls of other vertebrates.
