Etymology: "Akinetic" is simply a Greek-built formation: the prefix "a-" meaning "not" or "without" (from the negating prefix found in ancient Greek) joined to "kinetic." The prefix is the same one that gives English words such as "atheist" and "anarchy," and it comes from the Proto-Indo-European negating element *n̥-, which Greek reduced to a single vowel. The base is the ancient Greek verb "kīnéō," meaning "to move" or "to set in motion." From it Greek formed "kī́nēsĭs," "motion," and then "kinētikós," "concerning motion," which English later adopted as "kinetic." Akinetic therefore reads literally as "not moving," the opposite of "kinetic" in the sense of energy in motion. Because it is a deliberate modern combination of an old prefix and an old root, the word does not descend unchanged from antiquity; it was assembled from those parts in English. Its meaning stays close to the literal sense "unable to move," with the same structure as "amoral" or "asymmetric."
