Word Origin

tooth
tooth: [OE] Etymologically, a tooth is an ‘eater’. Its ultimate source is the prehistoric Indo- European base *ed- ‘eat’, which also lies behind English eat and edible. From this was formed the noun *dont-, *dent- ‘tooth’, whose descendants include Latin dēns ‘tooth’ (source of English dentist, indent, trident [16], etc), Greek odón ‘tooth’, (source of English odontology [19]), Welsh dant ‘tooth’, and prehistoric Germanic *tanthuz. This evolved into German zahn, Dutch, Swedish, and Danish tand, and English tooth. A variant of *tanthuz may lie behind English tusk.=> dentist, eat, edible, indent, odontology, trident, tusk
