Etymology

سِنّ comes from the Semitic root s-n-n, which carries the sense of sharpening or whetting. A tooth is the sharp thing in the mouth, so the noun and the verb to sharpen share one root. The same word runs across the Semitic family, from Hebrew shen to Akkadian shinnu. The verb سَنَّ, to sharpen or to set a precedent, belongs to the same family.
