Etymology: Pandiculation names the slow, full-body stretch that often comes with a yawn. The word is built from "pandiculate," a verb that itself rests on Latin roots, with the Latin "pandere" meaning "to spread out" or "to stretch." The verb is the base, and the noun is formed by adding the suffix "-ion," which turns an action verb into the name of the act. The suffix has a long path into English. It descends from the Latin "-tio," which was added to verb stems to name the act or process they describe, and it reached English through Old French "-ation" and Middle English "-acioun." Because the root is Latin, the word sounds technical, yet it describes an ordinary, almost universal physical habit.
