Irregular Plural or Mutating Plural
What is an Irregular Plural?
They are irregular nouns in the plural form. They are not regular because their plural form is different than just adding an “s” or “es” at the end of the word. In other words, irregular plurals are nouns that do not follow the usual rules for forming plurals in English. Most nouns form their plurals by adding -s or -es to the singular form, but this rule has many exceptions.
There are many other irregular plurals in English, and it’s important to learn the correct plural form of each noun in order to speak and write correctly. Like the table of irregular verbs, we can also create a table to study and visualize it.
Some of these words are very common and used on a daily basis, like: feet, teeth, men, women, children, and people.
