Incorrect use of 'is' vs. 'are'

Writers often pair the singular verb is with a plural subject-The books is-because of quick thinking, intervening words, or visual breaks. That mismatch breaks subject-verb agreement and reads as an error.

Below are tight rules, quick checks, many ready-to-use examples for work, school, and casual writing, simple rewrites, a short memory trick, and notes on spacing and hyphens that sometimes hide the real issue.

Quick fix

Use are with plural subjects: change "The books is" → "The books are." Identify the subject, decide whether it's singular or plural, then pick is or are accordingly.

Plural subject → are. Singular subject → is.
Ignore intervening phrases like of the, along with, or parentheticals when matching subject and verb.
Collective nouns depend on meaning: treat them as singular if you mean the group as one unit, plural if you mean the members.

The grammar core: why "The books is" is wrong

Verbs agree with their subjects in number. Is is third-person singular present; are is the plural present form. Because books is plural, the verb must be plural as well.

Modifiers and nearby nouns don't change the subject's number. Count the actual subject-then choose the verb.

Singular subject → is (The book is).
Plural subject → are (The books are).
Compound subjects joined by and take a plural verb (The book and the pen are missing).

Wrong: The books is on the desk.
Right: The books are on the desk.

Why this mistake happens

Three common causes:

Mental focus on one item: You picture a single title and use is by habit.
Intervening words: Phrases like along with or prepositional modifiers distract the eye from the true subject.
Spacing, punctuation, or typos: Missing spaces or line breaks can disguise the subject-verb link.

Wrong: The books, along with the DVDs, is missing from the shelf.
Right: The books, along with the DVDs, are missing from the shelf.

Quick checks to fix your sentence

Run this checklist in order and apply a small rewrite if needed.

Find the subject. Ask: is it one (singular) or more than one (plural)?
Ignore intervening prepositional phrases and modifiers between subject and verb.
Pick the verb form that matches the subject.
Read the sentence aloud-saying it helps you hear a mismatch.

Wrong: All the books is on the cart.
Right: All the books are on the cart.
Rewrite option: All of the books are on the cart. (Makes plurality obvious.)

Test the whole sentence, not just the phrase. Context often makes the correct verb clear.

Rewrite recipes: three quick rewrites for awkward sentences

If agreement still trips you up, rewrite to make the subject explicit.

Use demonstratives: Those/These books are...
Specify quantity: Several/Many books are...
Split long sentences so the subject sits next to its verb.

Rewrite:
Original: The books is expensive. → Those books are expensive.
Rewrite:
Original: The books is missing from my desk. → Several books are missing from my desk.
Rewrite:
Original: The books is on sale at the vendor. → The books are on sale at the vendor.

Memory trick

Ask "How many?" If the answer is more than one, use are. Quick test: "How many books?" → "More than one" → use are.

Another short cue: replace the subject with "those" or "that one." If "those" fits, then are fits; if "that one" fits, then is fits.

Spacing, punctuation, and hyphen traps

Sometimes the error is a typo or layout issue: missing spaces, line breaks, or misplaced punctuation hide the subject-verb relationship.

Check for missing or double spaces: "The booksis" is a typing error, not a verb choice.
Avoid breaking the subject and verb across lines if it creates confusion in short sentences.
Hyphenated modifiers describe units (a two-book set) but don't change the subject's number: the books are...

Wrong: The booksis missing from the shelf. (typing error)
Right: The books are missing from the shelf.
Wrong: She bought a two book set, and the books is heavy.
Right: She bought a two-book set, and the books are heavy.

Similar mistakes to watch for

These patterns cause the same confusion as "The books is." Apply the subject-verb check each time.

There's vs There are: There's two reasons → There are two reasons.
A number of vs The number of: A number of books are missing. The number of books is small.
Each/every/either/neither take singular verbs: Each of the books is marked.

Wrong: There's three books on the table.
Right: There are three books on the table.
Right: A number of books are overdue. (plural)
Right: The number of books is small. (singular)

FAQ

Is "The books is" ever correct?

No. "The books" is plural and requires the plural verb are. A similar-looking sentence can be correct if the subject is actually singular (e.g., The book is...).

Why do I hear native speakers say "there's" with plural nouns?

Casual speech often favors contractions like there's for speed. In careful speech and formal writing, use there are for plural nouns.

How can I quickly check subject-verb agreement?

Find the subject, decide if it's singular or plural, ignore modifiers, choose the matching verb, and read the sentence aloud.

What about "each of the books is"?

Words such as each, every, either, and neither take singular verbs: "Each of the books is labeled."

Will changing wording help when I'm stuck?

Yes. Rewrites like "Those books are..." or "Several books are..." remove ambiguity and make the correct verb obvious.

Want to check a sentence quickly?

If you're unsure, paste the full sentence into a grammar checker or read it aloud next to the subject. Small rewrites often fix the issue immediately.
