The Plural Forms of Words

What Are the Plural Forms of Words?

The word "plural" means "more than one in number." So, the plural form of the word "cat" is "cats," and the plural form of "mouse" is "mice." (Plural is the opposite of singular.)

The term "plural" does not apply to just nouns (e.g., cats, mice), it also applies to pronouns, determiners, and verbs. For example:

    Forming the Plurals of Nouns

    In most cases, a noun will form its plural by adding "s" to the singular form. For example:
    • 1 dog > 2 dogs
    • 1 house > 2 houses
    • 1 video > 2 videos
    The spelling rules for forming the plurals of nouns (e.g., whether to add "s," "es," or "ies") usually depend on how the noun ends. However, the ending can also depend on a noun's derivation (e.g., "stadia" is acceptable plural of "stadium" due to its Latin derivation). Here are some pages about forming the plurals of nouns: Warning: You must not insert your own apostrophe before the "s" when forming a plural. This is a serious grammar mistake.

    What Are the Plural Pronouns?

    The plural personal pronouns are "we," "you," and "they." They contrast with the singular personal pronouns, which are "I," "you," "he," "she," and "it." (NB: The personal pronoun "you" can be both singular or plural. That's because you can say "you" to mean one person or several.)

    Here are the personal pronouns in a table with their full names (plural pronouns shaded):
    Ifirst person singular
    Yousecond person singular
    He / She / Itthird person singular
    Wefirst person plural
    Yousecond person plural
    Theythird person plural

    What Is the Plural Form of a Verb?

    The plural form of a verb is the form that fits with a plural subject. In this table, the plural verbs are shaded in gray.

    Wefirst person pluralWe ateWe eatWe will eat
    Yousecond person pluralYou ateYou eatYou will eat
    Theythird person pluralThey ateThey eatThey will eat

    English is unusual because the singular and plural forms of verbs in each tense are identical. The only exception is the third-person-singular form in the present tense (shown in red). This is why English is easier to learn than many other languages. In most other languages, there would be a different spelling in every single box in the table above.

    What Are Plural Demonstrative Determiners?

    The demonstrative determiners (called demonstrative adjectives in traditional grammar) are "this," "that," "these," and "those."

    The singular ones are "this" and "that." The plural ones are "these" and "those."

    This is worth knowing because "these" and "those" must be paired with a plural word. In others, you cannot say:
    • These kind of things. wrong cross
    You must say:
    • These kinds of things. correct tick

    Forming the Plurals of Foreign Words

    Words "stolen" from other languages form their plurals in a variety of ways. Examples:
    • stadium > stadia or stadiums
    • (Through common usage, the plural "stadiums" is acceptable too.)
    • datum > data
    • radius > radii or radiuses
    • (Through common usage, the plural "radiuses" is acceptable too.)
    • agendum > agenda
    Here is a list of awkward plurals in English.

    "Plural" Also Applies to Zero

    Somewhat counter-intuitively, the word "plural" also applies to zero. Look at this list.
    • 0 dogs (plural)
    • 1 dog (singular)
    • 2 dogs (plural)
    • 3 dogs (plural)
    Now look at this example:
    • There are no alligators in the lake.
    • (Note that "no" attracts the plural verb "are" and the plural noun "alligators.")
