Etymology: Tuneability is a straightforward construction: the English adjective "tune" (to bring an instrument or engine into proper adjustment) with the suffix "-ability," which turns an adjective into a noun meaning the quality of being able to be acted on in that way. The base "tune" has a long ancestry, ultimately tracing to Greek "tonos," meaning a stretching or tension, which is why the same root gives us "tone" and "tonic." The musical sense of the word came into English in the Middle Ages, and the modern sense of adjusting a machine for better performance developed from it. The suffix is the more interesting part. "-ability" reached English through Middle French from Latin "-abilitas," built on "-abilis," a formative meaning "able to be." English has long attached it to verbs of action, producing words such as "readability" and "usability." "Tunability" is the form most dictionaries prefer, while "tuneability" keeps the spelling of the base word, a variant that follows the same pattern.
