forty-sixth

The word "forty-sixth" is a modern English compound ordinal number, formed by combining the cardinal base "forty" with the ordinal suffix "-sixth." "Forty" itself derives from Old English "feowertig," a compound of "feower" (four) and "tig" (a group of ten), reflecting the Germanic decimal system. "Sixth" originates from Old English "sixta," the ordinal form of "six," with the "-th" suffix being the standard Germanic marker for forming ordinals. The logic of the compound is purely arithmetic and positional, designating the item occupying the position number forty-six in a series, following the consistent pattern of English ordinal formation.

Structure: forty (40) + sixth (6th) forty (from Old English 'feowertig', meaning four tens, of Germanic origin); sixth (from Old English 'sixta', meaning ordinal of six, of Germanic origin).
