eixes

Eixes is a term that may appear in Catalan-language texts as the plural form of eix, a masculine noun meaning axis or reference line. The standard plural in modern Catalan is eixos. The form eixes is uncommon in contemporary standard usage and is typically considered a nonstandard variant, a regional spelling variant, or a historical orthographic form. In some dialects or older writings, eixes has appeared as the plural of a feminine noun eixa, but in current Catalan there is no widely accepted feminine form of eix for this sense.

In usage, eixos denote lines or directions around which measurements, rotations, or symmetry are organized. They appear in mathematics, physics, geography, engineering, and computer graphics to indicate principal directions, lines of reference, or axes of rotation. For example, one might refer to the major eixos of a coordinate system or the symmetry eix of an object.

Origin and etymology: eix comes from Latin axis, adapted into Catalan through historical sound changes. The expected plural form aligns with Catalan pluralization patterns as eixos, while eixes survives mainly as a historical or regional variant rather than a standard lexical entry. When encountered in modern texts, eixes is usually a variant spelling rather than a distinct term with a separate meaning.
