one-sixteenth

The word 'one-sixteenth' is a transparent numerical compound formed within Modern English. Its first element, 'one', descends from the Proto-Germanic 'ainaz', which is also the source of the numeral across Germanic languages. The second element, 'sixteenth', is built from the cardinal 'six', from Proto-Germanic 'sehs', combined with the ordinal suffix '-teenth', a variant of '-tenth' derived from Old English '-tēoþa'. The compound's logic is purely arithmetic, directly stating a single unit out of sixteen total equal parts, with the '-teenth' suffix systematically forming the ordinal numbers from thirteen onward to denote fractional division.
