pneumonoultramicroscopicsilicovolcanoconiosis这个由45的字母所构成的单字，要在毫无规则可循的情况下，叫一个20岁以上，脑筋已经开始僵化的人记下来，实在非常困难。一般人看了只有猛摇头的份。所以，我们应该找出线索来帮助记忆。这个乍见十分冗长的单字，其实仔细观察可以发现是由几个部分构成。pneumono
…………「肺」→
这个单字可以衍生出pneumonia(肺炎)ultra
…………「超」micro
…………「微」→
microscope(显微镜)scopic
…………「视」silico
…………「矽」→
silicon(矽)volcano
…………「火山」coniosis
…………「症」只要将上述七个部分组合起来，就能了解这个字的字义，也就是「矽肺症」。
