是的。
Word family中文译作“词族”，是一系列有规律的单词。它的规律体现在这些单词在构词上有着相同的词尾。 比如下面这个句子：Pam，Sam和yam就都属于-am词族。
每个“词族”里都有一串“兄弟姐妹”词儿，比如：
air as in air, chair, fair, hair, pair ...
are as in care, scare, share ...
ead as in bread, dead, head, read, thread ...
ear as in dear, ear, hear, near, tear, year ...
ind as in find, kind, mind, wind…
