英文词源
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
