The word "ninetyfold" is derived from the combination of two parts: "ninety" and "fold".
The term "ninety" comes from the Old English word "nigontig", which means "nine tens". It is formed by combining "nigon" (nine) and "tig" (ten). The Old English "nigon" can be traced back to the Proto-Germanic word "*newun", which shares the same meaning of "nine". Ultimately, this can be linked to the Proto-Indo-European root "*h₁néwn̥", also signifying "nine".
The second element, "fold", originated from the Old English word "feald", which means "fold", "pleat", or "multiply".
