The word "parity" originates from the Latin paritas, derived from par (meaning "equal"). The root par also appears in words like "compare" (to assess equality) and "disparity" (inequality). The suffix -ity converts the adjective "par" into a noun, emphasizing the abstract concept of equality. Over time, "parity" expanded from general equality to specialized uses in mathematics and computing, reflecting logical consistency or balance.
