Where does the word tooth come from?

The Word "tooth" originates from the Old English term "tōþ," which is related to similar Words in other Germanic languages, such as Old High German "zāhz" and Dutch "tand." Its roots can be traced further back to the Proto-Germanic Word "*tanþs," which is derived from the Proto-Indo-European root "*h₁ed-," meaning "to eat." This etymology reflects the tooth's primary function in the process of eating.
