For example, in front of " s" words, there may be an " i" placed involuntary, without their meaning to.

例如，在“s”字的前面，可能会不自觉地放一个“i”，没有它们的意思。

So we've been talking about regular plurals where you take a word and you add an S. So for example, the word dog becomes dogs.

所以我们一直在谈论常规的复数形式，你可以在其中加上一个 S。例如，dog 这个词变成了 dogs。
