diamond-dictionary：钻石是金属吗？
【造词理据】源自PIE词根*deme-（驯服的、限制、强制），D表门，引申指家养的、驯服的，再抽象指制服、强制。diamond丢失了前缀a-，表否定，所以diamond原指难以驯服的，后指坚硬的、难以折断的，这里指难以折断的、坚硬的钻石。-ond是名词后缀。
【例句】Take a long drive with no music on. Plunge deep into your own thoughts. Examine your ideas as if you are scrutinizing a diamond for quality. 长时间的驾驶不要开音乐，你自己的思考要深刻，要像仔细检查钻石的质量一样来审视自己的思想。
【同根词】diamond、adamant、timber、turd
【造词理据】想象。源自PIE词根*dyeu-（闪耀），D形模仿闪耀着光的太阳，比喻指类似日晷的东西，借指一天、白天（day），在这里指日记、日记本等。
【例句】When I looked that day up in my diary, I found that I had noted it down as "a very empty day" when it rained and nothing much happened. 当我查看那天的日记时，发现我是这样写的“非常空虚的一天”，下过雨，没有发生什么事。

【造词理据】拟声。模仿人严肃的说话时发出低沉的声音，借指说话，后指口授、听写。
【例句】I'm afraid that is exactly the problem with your dictation, never trying to make sense of what you hear. 我认为，你听写的问题在于不去理解所听的内容。-ation是后缀。
