(I CANT FIND THE ANSWER DEPENDING ON THE DEFINITIONS ON THE PAPER AND ONLINE)
Irregular plural nouns are "irregular" nouns "in plural form". It's "a noun that becomes plural by changing" the "spelling in other ways than" just "adding an “s” or “es” to the end of the word". There are lots of ways for these changes that can happen.
Some "take on the plural form by first changing the last letter of the word". This is "before adding" a “s”. Words ending "in “f” are a good example of this case". To make this "word plural, you change the “f” to “ve” and add a “s”".
Here's a list of some irregular plural nouns:
-ves plural nouns:
elf - elves
calf - calves
knife - knives
loaf - loaves
shelf - shelves
wolf - wolves
Changing into plural nouns by changing vowels, words, or adding different ending:
man - men
person - people
mouse - mice
child - children
foot - feet
goose - geese
tooth - teeth
louse - lice
cactus - cacti
appendix - appendices
ox - oxen
Some irregular plural nouns with "the same spelling as" singular form. These are like "scissors, pants, bison, deer, and sheep". Some "animal nouns" turn "plural" by having the "same spelling as the singular form" or adding "es" or "s"" Examples:
cod - cod or cods
shrimp - shrimp or shrimps
fish - fish or fishes
quail - quail or quails

I hope this helps! :)
The -en to form the plural of "ox" is the irregular. The ending -en also shows up on children, men, and women.
Regular plurals are those that have -s or -es as their endings.
