Etymology: "Osculator" is a straightforward formation: it is the English word "osculate" with the agent suffix "-or" added, meaning one who performs the action. "Osculate" itself comes from the Latin "osculari," meaning to kiss, and the Latin root "osculum," a little mouth or kiss, is a diminutive of "os," meaning mouth. The suffix did most of the travelling. It descends from a Proto-Indo-European agent ending that passed into Latin as "-tor" and then "-ator," reached Old French as "-eor," and entered Middle English as "-our," which English later spelled "-or." English has since attached this same ending to countless verbs, so "osculator" follows a very common pattern.
