  • What are singular nouns?

    Singular nouns definition

    Singular nouns are used to refer or identify only one person, animal, quality, thing, place, or an idea. They provide the stem based on which a plural noun can be formed. Often the determiners "a", "an" or "the" are placed before them in a sentence.

    What are plural nouns?

    Plural nouns are used to refer or identify more than one person, animal, quality, thing, place, or an idea. Through the use of the singular pronoun stem and several variations of suffixes, the plural nouns are formed. 

    How to form plural nouns

    The most common method to turn a singular noun into a plural noun is by adding an "-s" to them.

    Singular Plural
    Rope Ropes
    Climber Climbers
    Bag Bags

    enlightenedWarning: However, there are exceptions to the rule that we will show you below.

    Singular nouns ending with "f" or "fe"

    If the singular noun end with either "f" or "fe" they are exchanged by "ve" prior adding the plural "-s".

    Singular Plural Exceptions
    Wife Wives Chefs
    Knife Knives Beliefs
    Wolf Wolves Roofs

    Singular nouns ending with “s”, “ss”, “sh”, "z", "o" “ch”, “x”

    If the singular noun contains one of these endings there is an "-es" added after them to form their plural form.

    Singular Plural
    Bus Buses
    Glass Glasses
    Dish Dishes
    Blitz Blitzes
    Tomato Tomatoes
    Crutch Cruches
    Box Boxes

    Singular nouns ending with "y"

    If the singular noun ends with a "y" and the letter before it is a consonant it is replaced by "ies" to form the plural form. If the letter before it is a vowel you only need to add an "-s".

    Singular Plural
    Baby Babies
    Party Parties
    City Cities
    Kitty Kitties
    Boy Boys
    Toy Toys

    Singular nouns ending with "sis"

    If the singular noun ends with a "sis" it is replaced by "ses" to form the plural form.

    Nouns that are only plural

    In English, there are a few word exceptions that are only in plural form and have no singular form.
