The word "nineteenth" combines "nineteen" (itself from Old English "nigon" [nine] + "tīene" [ten], reflecting the base-10 counting system) with the ordinal suffix "-th" (from Old English "-þa"). This structure follows the consistent Germanic pattern for forming ordinal numbers (e.g., "fourth," "tenth"). The "-th" suffix transforms cardinal numbers into ordinals, emphasizing sequence or position.
