Shing! Snkt! Kachow! Oh no, it’s a knife and it’s really sharp watch out oh nooo
Nah, it’s just etymology corner. Let’s talk about sharp things! Sharp is a Germanic word from the Proto-Germanic *skarpaz. If we dial it back to the Proto-Indo-Europeans, we get *sker- meaning “to cut”. That influences a ton of words, like a screw, which cuts into wood as it is applied.
