Etymology: "Axises" is the plural of "axis," so its history is the history of that base word. "Axis" was borrowed into English from Latin "axis," which meant an axle or pivot, and the Latin word itself ultimately comes from a Proto-Indo-European root linked to the idea of turning or rotating around a fixed point. The plural is formed in the regular way, with "-es" added to a noun ending in "-is," and the plural of "axis" is more commonly "axes," a form that sounds the same as the plural of "axe." Using "axises" is an accepted but less common alternative, and it is the form most often seen in discussions of coordinate systems, where several reference lines are each called an axis. Mathematicians and engineers use the term in that sense, as a line of reference against which positions or motions are measured.
