Is vs. Are – Which is Correct?

When two nouns are joined by and and name separate people, places, things, or ideas, use are: “The manager and assistant are here.” Use is when the nouns form one combined unit, title, quantity, or idea: “Macaroni and cheese is popular.” Context determines agreement, not simply the number of nouns.

Is or Are: Which Is Correct?

Both “is” and “are” are correct, but they serve different grammatical purposes. Use are with two nouns joined by and when the nouns refer to separate subjects. Use is when the nouns describe one combined idea, one title, one amount, or a singular subject with an additional phrase.

For example, “The teacher and student are talking” refers to two people. However, “Bread and butter is my usual breakfast” treats the two foods as one combined meal. If two nouns are joined by or or nor, the verb generally agrees with the noun closest to it: “The manager or the employees are responsible,” but “The employees or the manager is responsible.”

The Best Trick to Remember the Difference

Use the separation test: replace the two nouns with they. If “they” makes sense, use are. For example, “The dog and cat are sleeping” becomes “They are sleeping.” If the nouns represent one thing, one unit, or one idea, use is: “Peanut butter and jelly is a classic sandwich filling.” You can also remove the second noun. If the remaining subject is singular, is may be correct.

How to Use Is

Is is the present-tense, third-person singular form of be. Use it with singular nouns, singular pronouns such as he, she, and it, and subjects that are treated as a single unit. When two nouns are connected by and, is is appropriate if the nouns form one established combination, one title, one quantity, or one conceptual whole.

Do not automatically use are merely because two nouns appear in the sentence. First determine whether the nouns represent two separate subjects or one combined subject.

Example 1: Fish and chips is a popular dish in many countries.

Example 2: The author and illustrator of the book is speaking at the event.

Example 3: Twenty dollars is enough for lunch.

What Are the Different Forms of Is?

Is is an irregular form of the verb be. The principal forms are be, am, is, are, was, were, being, and been. Use is with singular third-person subjects in the present tense: “She is ready” and “The machine is working.”

In contractions, is commonly becomes ’s, as in “The book’s interesting,” or combines with not to form isn’t. The past-tense equivalent is usually was: “The plan was successful.”

Etymology of the Word Is

Is comes from Old English is, a form of the verb meaning “to be.” It is related to similar forms in other Germanic languages, including German ist and Dutch is. The verb be preserves several forms from different historical roots, which explains its irregular conjugation.

How to Use Are

Are is a present-tense form of be. Use it with plural nouns and with the pronouns you and we. When two nouns joined by and refer to separate people, objects, or ideas, they create a plural subject and require are.

Use are when each noun can be understood as performing the action or having the stated condition independently. The sentence “The coach and players are ready” means that the coach is ready and the players are ready.

Example 1: The manager and assistant are reviewing the schedule.

Example 2: Apples and oranges are available at the market.

Example 3: The cause and effect are difficult to separate in this case.

The negative contraction is aren’t, as in “They aren’t available.” In the past tense, plural subjects generally take were: “The students were studying.”

Etymology of the Word Are

Are developed from historical forms of the verb be. Its precise history reflects the blending of several Old English and later Germanic forms. Related forms appear in languages such as German sind and Dutch zijn, although modern English uses are in a different grammatical pattern.

Related Concepts

Understanding subject–verb agreement makes it easier to choose between is and are. The key issue is whether the grammatical subject is singular, plural, or being treated as one unit.

• Subject–verb agreement: A verb should match its subject in number. Singular subjects generally take is, while plural subjects generally take are.
• Compound subjects: Two nouns joined by and usually form a plural subject and take are. However, a compound expression treated as one unit may take is.
• Collective nouns: Words such as team, family, and committee are usually singular in American English when the group acts as one unit: “The team is ready.”
• Subjects joined by or or nor: The verb often agrees with the noun closest to it: “The teacher or students are presenting” and “The students or teacher is presenting.”
• Amounts and measurements: A sum, period, distance, or measurement treated as one amount usually takes is: “Ten miles is a long walk.”

Examples from Media and Literature

The following examples reflect common constructions found in headlines, publishing, entertainment, and everyday discussions of literature. They show how the intended meaning determines the verb.

• Titles: “The Lord of the Rings is a famous fantasy series.” A title is treated as one singular work, even if it contains a plural noun.
• Film and television: “The director and lead actor are attending the premiere.” These are two separate people, so the plural verb are is required.
• News reporting: “The mayor and city council are considering the proposal.” The mayor and council are presented as separate participants.
• Literary themes: “Love and loss are recurring themes in the novel.” The sentence discusses two distinct themes.
• Combined concepts: “Bread and butter is a familiar breakfast combination.” The phrase refers to one customary food pairing.

Frequently Asked Questions

Question 1: Should I use “is” or “are” after two nouns joined by “and”?
Usually use are because two separate nouns joined by and create a plural subject. Use is when the nouns express one combined unit, title, amount, or idea.

Question 2: Is “macaroni and cheese is” grammatically correct?
Yes. In “Macaroni and cheese is popular,” the food combination is treated as one dish. If the sentence refers to separate portions or items, are may be appropriate: “The macaroni and the cheese are in separate containers.”

Question 3: Does the word closest to the verb determine whether I use “is” or “are”?
Not when the nouns are joined by and. The entire compound subject normally determines agreement. With or or nor, however, the verb commonly agrees with the subject closest to it.
