Rules of Forming Singular Noun to Plural Nouns

Singular Noun and Plural Noun:

  1. Singular Noun: A singular noun refers to a single person, place, thing, or idea. It represents only one item or individual. For example, "dog," "book," and "table" are singular nouns because they indicate a single dog, a single book, and a single table, respectively.

  2. Plural Noun: A plural noun, on the other hand, refers to more than one person, place, thing, or idea. It represents a group or multiple items. Plural nouns are formed by adding an "-s" or "-es" to the end of the singular form in most cases. For example, "dogs," "books," and "tables" are plural nouns because they represent more than one dog, book, and table, respectively.

It's important to note that there are irregular plural forms in English that don't follow the standard "-s" or "-es" rule. Examples include "children" (plural of "child"), "mice" (plural of "mouse"), and "men" (plural of "man").
