简单的说：单词的上下义,就类似分支.但是这种上下义关系是相对存在的. 比如：animal, cat,dog,(animal,是后两者的上义,cat,dog就是animal的下义词) 又如：fruit, apple,这里fruit就是apple的上义,apple就是fruit的下义词. 希望这样的说明对你有帮助.

您指的应该是“上义词”和“下义词”吧。上义词是对事物的概括性、抽象性说明；下义词是事物的具体表现形式或更为具体的说明。可以理解为，上义词针对共性，而下义词针对个性。例如：动物（animal）和鸟（bird）——其中，animal是上义词，而bird是下义词。动物（animal）的也有上义词，就是生物（organism）。
