Rules for Using Countable Nouns
Countable nouns follow specific grammar rules regarding singular and plural forms, article usage, and quantifiers. Here’s a breakdown of the key rules:
1. Singular and Plural Forms of Countable Nouns
Countable nouns have distinct singular and plural forms. The plural form is usually created by adding -s or -es, but some nouns have irregular plural forms.

2. Using Articles with Countable Nouns
Singular countable nouns must have an article (a or an) or another determiner (this, that).
Plural countable nouns do not require an article when referring to things in general but can use the for specific reference.
