Etymology

The word "seventy" combines the Old English root "seofon" (seven) with the suffix "-tig," which denoted multiples of ten (e.g., twenty, thirty). This suffix evolved from Proto-Germanic *-tigaz, related to the concept of "ten" or "decade." Over time, "seofontig" in Old English simplified to "seventy" and later "seventy," aligning with the pattern of other decade numbers (e.g., sixty, eighty). The structure reflects a straightforward numerical composition: 7 (seven) × 10 (ty).
