The word "seventieths" is derived from the combination of two elements: "seventy" and "-ths".
"Seventy" is the cardinal number that represents the quantity 70. It is traced back to the Old English word "hundseofontig", which is a combination of "hund" (meaning "hundred") and "seofon" (meaning "seven"). "Hundseofontig" gradually evolved into "seventig" in Middle English, and eventually became "seventy" in Modern English.
The suffix "-ths" is added to a cardinal number to indicate fractions or multiples of that number. It originates from the Old English suffix "-tha", which was used to derive ordinal numbers. Over time, it evolved into the Modern English suffix "-th", which serves the same purpose.
