Etymology Origin:
The word axis traces back to Latin axis, originally referring to the axle of a wheel or the celestial pole. Over time, it expanded to denote any central line of rotation or symmetry. The Latin root is linked to Proto-Indo-European h₂eḱs- ("axis"), reflecting its ancient association with pivotal structures. The term’s geometric and organizational meanings emerged later, preserving the core idea of a central reference.
