Etymology: "Scalability" is a plain compound built from two pieces of English. The first is "scale," which comes from Latin "scala," meaning "ladder" or "staircase," and which reached English through Old French "escale." The sense of a graded series of marks, as on a measuring instrument, grew out of that idea of rungs in order. The second piece is the suffix "-ability," which turns an adjective into a noun for the quality of being able to do something. So "scalable" describes something that can be climbed to a larger size, and "scalability" names the quality of being scalable. The word may have been formed in one of two ways. Either "scalability" was built directly from "scale" and "-ability," or it came from the adjective "scalable" with the noun suffix "-ity." Both routes lead to the same result, and the source does not settle which came first. The meaning has also narrowed over time. Its earliest uses were general, referring to anything that could be scaled, such as a height or a measured amount. Its main modern use is in technology and business, where it describes whether a system keeps working well as its load, users, or demands grow.
