Morphology
ethmoid = ethmo + oid
The root 'ethmo-' is a specialized combining form (not a standalone English word) meaning 'sieve-like', so the anatomical sense is not transparently derivable by a typical learner from its parts.
Etymology
The word ethmoid comes from Greek ethmos, meaning 'sieve', and the ending -oid, meaning 'like'. The bone is full of many small holes so it is 'sieve-like', which is why it is a light, spongy bone between the eyes that helps form the nose area.
