non-functioning

The word "non-functioning" is a modern English compound adjective built from clearly defined components. The core noun "function" originates from the Latin functio, derived from the verb fungi meaning "to perform or execute." The prefix "non-," also from Latin, is a straightforward negator, directly appended to the base word. The suffix "-ing," of Germanic origin, is added to the verbal stem "function" to form a participial adjective, describing the state of "not performing." The logic of the word is transparent: it literally describes the state of "not performing its intended work," a meaning that has remained consistent from its constituent parts to its modern abstract use for anything inoperative.
