Etymology: "Usability" is a plain formation: it combines "usable" with the suffix "-ity," which turns an adjective into a noun for a quality or state. "Usable" itself comes from "use" plus "-able," meaning capable of being used. The result is a noun for the quality of being usable, which is why it can be read as a straightforward build from two familiar parts. The word's modern sense, a measure of how easily people can accomplish tasks with a product, is a later and more specialised extension of that literal meaning. Ordinary "usability" simply means the quality of being usable at all, and the narrower sense of how well a product suits its users grew out of that general idea.
