Regular Nouns:
Regular nouns follow the standard rules of pluralization in English. This typically means adding "-s" or "-es" to the singular form.
Examples:
* Singular: cat, dog, book, chair, tree
* Plural: cats, dogs, books, chairs, trees
* Singular: box, brush, watch, church
* Plural: boxes, brushes, watches, churches
Irregular Nouns:
Irregular nouns do not follow the standard rules of pluralization. They have unique and often unpredictable plural forms.
Examples:
* Singular: child, woman, man, tooth, goose
* Plural: children, women, men, teeth, geese
* Singular: mouse, ox, foot, louse, die
* Plural: mice, oxen, feet, lice, dice
Other notable examples:
* Singular: sheep, deer, fish, series
* Plural: sheep, deer, fish, series (these words have the same form in both singular and plural)
* Singular: person
* Plural: people (a completely different word!)
Remember: There are exceptions to every rule, so sometimes the best way to know the plural form of a noun is to simply look it up!
