Adenoid

/ˈædɪnɔɪd/noun

The mass of lymphoid tissue at the back of the nose, usually spoken of in the plural.

The Greek roots

ἀδήν
adḗn
gland
+
εἶδος
eîdos
form, appearance

Literally: gland shaped

The story of the word

The word arrived in the nineteenth century as an adjective for tissue that looked glandular under the knife. It is not glandular, so the name preserves a nineteenth-century mistake. The plural noun came into common speech only once surgeons started removing the things, which is why a child can be described as having adenoids as though nobody else does.
