Etymology

The word "sixteenth" combines "sixteen," derived from Old English "sixtīene" (six + ten), with the ordinal suffix "-th," used to form sequence numbers (e.g., fourth, fifth). The suffix traces back to Proto-Germanic *-dô, marking order or division. This structure reflects a consistent Germanic pattern for creating ordinal numbers by adding "-th" to cardinal bases.
