How the patterns shape this root
سَبْعَة is seven, سَابِع (فَاعِل) is seventh, and the week, أُسْبُوع, is simply 'a seven' of days, plural أَسَابِيع; أُسْبُوعِيّ is weekly. The ordinal numbers all use the doer pattern فَاعِل — ثَالِث، رَابِع، خَامِس، سَابِع — as if the seventh were 'the one doing seven'. The tens add ـُونَ: سَبْعُونَ, seventy.
