Irregular plurals, unlike regular plurals, don’t necessarily follow any pattern, and require a lot of memorization. Mastering this type of pluralization uses a different region of your brain than regular pluralization, meaning it’s an entirely different skill set than regular pluralization. So don’t get too frustrated if you can’t remember the correct plural. If you’re ever in doubt, the dictionary is there for you. Below are some common patterns in irregular plural nouns.
