The Noun Number (Singular, Plural) Rules

The number means indicating one or more than one noun. Two numbers exist in our language, singular, and plural.

A noun that denotes only one person, thing, or place is known as a singular noun—for example, chair, student, book, class, city, country, match, etc.

A noun that expresses more than one person, place, or thing is known as a plural noun—for example, catches, feet, hands, roofs, chairs, glasses, etc.

Rules of Forming the Plural of a Noun

Noun Number Rule-1:

Most nouns can be made plural when “s” is added to the singular noun.

Nouns ending in a vowel (a, e, i, o, u) + “-y” can be converted to plural form by adding “s” to the singular.

Noun Number Rule-4:

Nouns ending in “y” proceeded by consonant form plurals by dropping “y” at the end and adding “-ies” instead of it.

Noun Number Rule-5:

Nouns ending in “o” form the plural by suffixing “es.”
