Etymology

Introduced by Frederik Ruysch in the 18th century, originally referring to the covering of small "nipples" of tissue on the lip. Initially a first-declension noun epithēlia, from Ancient Greek ἐπι- (epi-, “on, atop”) +‎ Ancient Greek θηλή (thēlḗ, “nipple”) +‎ -ia; the nominative singular was later reinterpreted as a second-declension neuter plural.
