Etymology: "Waterbottle" is simply a closed-up spelling of "water bottle," the two words joined into one. "Water" comes from Old English "wæter," a word shared with German "Wasser" and Dutch "water," while "bottle" traces through Old French "boteille" to Medieval Latin "buticula," a diminutive of "butis," a cask or vessel. Put together, the compound names a bottle meant for water, a container defined by its contents. The spelling is the only real variation here. Writers and dictionaries have tended to keep the two words separate, and the joined form is a looser, less formal version of the same thing. Its meaning has stayed fixed on the portable drink container, so the story is less about change than about the two parts of the word doing exactly what their names suggest.
