Definitions

1. Describing a process or device that requires manual operation rather than functioning by itself; indicating something that does not operate automatically and depends on human control; referring to an action or mechanism that is deliberately not automatic
2. Characterizing systems, equipment, or procedures that demand direct human intervention instead of self-governing operation; pertaining to actions that must be performed manually instead of autonomously; relating to non-self-activating functions requiring user input
3. Applying to methods or machines needing conscious and deliberate human effort to function without automatic control; signifying processes that do not proceed by themselves but rely on manual management; defining operations absent of automatic execution and dependent on human involvement

Etymology: The word is a plain compound: the prefix "non-", meaning "not", attached to "automatic". "Automatic" itself comes from the Greek "automatos", meaning "self-acting" or "acting of its own will", built from "autos" ("self") and a root related to "matos" ("thinking, willing"). So the core idea is something that moves by its own inner mechanism. Negating it gives a thing that needs an outside agent, a person's hand or effort, to make it go. The pairing is most useful in technology, where "automatic" became the standard word for machines that run themselves, such as automatic transmissions and automatic rifles. "Nonautomatic" then describes the older or simpler alternative: a manual gearbox, or a camera where the photographer sets the exposure. The word is less a separate concept than a label defined against the automated version.
