WHAT are irregular plural nouns?

EXAMPLES OF IRREGULAR PLURAL NOUNS
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”.

*more than one knife=knives
*more than one loaf=loaves

*more than one man=men
*more than one person=people
*more than one child=children
