Explanation:
Not all words that has "S" in the last word is plural because Always use “S” with countable nouns when it’s plural.
Countable nouns (or count nouns) are those that refer to something that can be counted. They have both plural and singular forms, examples girl/girls, apple/apples, cat/cats, house/houses, etc. In the singular form, the article A or AN comes before them.
Uncountable nouns are for the things that we cannot count with numbers. They are names for ideas, qualities, or physical objects that are too small or too big to be counted. Examples are liquid, powder, gases, etc. Uncountable nouns are used with a singular verb.
