Irregular Plurals
Explanation:
An irregular plural noun is an irregular noun in the plural form. An irregular noun is a noun that becomes plural by changing it’s spelling in other ways than adding an “s” or “es” to the end of the word. This change can happen in a variety of ways. Some irregular nouns take on the plural form by first changing the last letter of the word before adding “s.” Words that end in “f” are a good example of this case. To make such a word plural, you change the “f” to “ve” and add an “s.” Some irregular plural nouns have the same spelling as their singular form such as scissors, pants, bison, deer, and sheep. Some animal nouns become plural by keeping the same spelling as the singular form or by adding an s or es.
