Etymology: The word is a plain compound: "bottle" plus "neck," meaning the narrow top of a bottle that slows whatever is poured through it. The image of a bottle's constricted opening is what gives the term its sense of a choke point in a system. The bottle half has a long pedigree. It descends from Latin "buttis," a cask or vessel, which gave rise to Late Latin "butticula," a small flask. Old French "boteille" carried it into Middle English as "botel," and the spelling settled into "bottle" in English. The neck half is much older, traceable through Old English "hnecca" to a Germanic root shared by many languages, and it has always meant the narrow part connecting a head or container to its body. Put together, the phrase kept its literal sense for centuries: a bottle with a narrow neck pours slowly, because liquid must squeeze through the constriction. Extending that picture to roads, factories and computer networks is a natural metaphor, and the compound now usually describes any stage where work backs up because everything must pass through it.
