Etymology: "Osculatio" is a Latin noun meaning "a kissing," formed from the verb "osculari," "to kiss," which in turn comes from "osculum," "little mouth" or "little face." The diminutive ending "-culum" makes "osculum" a small version of "os," the word for mouth or face, so the original sense is closer to "a little mouth" than to anything romantic. Romans used "osculum" for a kiss itself, and its diminutive character reflects the affectionate, gentle tone the word carried. English borrowed the Latin form directly, and it appears in learned writing as a formal or mock-formal term, rather than in everyday speech. The Latin "osculum" also gave English the adjective "osculatory," used for things that relate to kissing or touching, and the word "osculation" has been used in mathematics for two curves that touch at a point with a high degree of contact. That geometric use owes nothing to romance and shows how a word for a kiss can end up describing a shared point between lines.
