* Noun: A word that names a person, place, thing, or idea.
* Singular: Refers to one item or individual.
* Plural: Refers to more than one item or individual.
How to form plural words:
* Adding "-s" or "-es": Most nouns form their plural by adding "-s" (e.g., cat - cats, book - books). Some nouns ending in "-s," "-x," "-ch," "-sh," or "-z" add "-es" (e.g., bus - buses, box - boxes, church - churches).
* Changing the ending: Some nouns have irregular plural forms (e.g., child - children, tooth - teeth, man - men).
* Staying the same: A few nouns have the same form in both singular and plural (e.g., sheep, deer).
Example:
* Singular: dog
* Plural: dogs
In short: Plural words are the forms of nouns that indicate there is more than one of the thing being named.
