注释

Eating, biting, teeth, and dentists are all related, as is well known, but the relationship goes further than one might think, that is, into the roots of the words eat, tooth, and dentist. The Proto-Indo-European root .ed-, meaning “to eat” and the source of our word eat, originally meant “to bite.” A participial form of .ed- in this sense was .dent-, “biting,” which came to mean “tooth.” Our word tooth comes from .dont-, a form of .dent-, with sound changes that resulted in the Germanic word .tanthuz. This word became Old English t?h and Modern English tooth. Meanwhile the Proto-Indo-European form .dent- itself became in Latin d?s (stem dent- ), “tooth,” from which is derived our word dentist. We find a descendant of another Proto-Indo-European form ·(o)dont- in the word orthodontist.

我们都知道吃、咬、牙齿、牙医都是紧密相联的，但它们之间的关系比我们所想象的还有紧密，甚至eat，tooth 和 dentist 的词根也互相联系。 在原始的印欧语系中，词根ed- 的意思是“吃”， 我们的eat 这个词的原意是“咬，啃”。 作为这个意思的-ed 的分词形式是 dent- ，意为“咬”， 后来转变成“牙齿”的意思。现在tooth 这个词来源于 dont- ， dent- 的一个变形， 随着声音的变化，这个词在日耳曼语言中成了tanthuz 。 然后，由这个词产生了古英语的toth 和现化英语的 tooth 。 同时dent- 这一原始印欧词语在拉丁语中变成了 dens （词根 dent- )， 意为“牙齿”，由此衍生出dentist 这个词。 在orthodortist 这个词中，我们可以发现，这个原始印欧语言的另一形式 (O)dont- 的踪影
