In English, most nouns become plural by adding -s at the end, like cat to cats. But some nouns are special. They are called irregular plural nouns. These words do not follow the normal rule. Instead, they change their form in different ways. For example, one man becomes two men, not two mans. Another example is one child becoming two children. There is no simple rule for these words, so it is important to learn them one by one. Understanding irregular plurals helps you speak and write English correctly from the start. This lesson will show you the most common irregular plural nouns.
