联想记忆法1
coal在古英语中写作col，意思是“一块燃烧着的没有火焰的炭”。
而charcoal（木炭）则是charred coal，即“烧制的炭”。
或者你这么联想试一试：c=h，所以变成hoal这个字母组合的中文发音有点像：火。火烧起来和煤烧起来是一样的。

小知识
Coal is a mineral, a black rock that can be extracted from the earth and burned for fuel. Most of the electricity that's produced in the world is powered by the burning of coal.
Coal may seem like an old-fashioned fuel, making you think of steam locomotives that ran on coal, or coal fires heating homes in the nineteenth century. Some people still burn coal in stoves today, although most coal is burned on a much larger scale, generating electricity for entire towns and cities. You can also use the noun coal to mean a glowing ember in your fireplace or backyard grill. In Old English, it was col, from a Germanic root.
