sky scraper (skyscraper)

Small slips-writing "The dog is" when you mean "The dogs are" or vice versa-change meaning and tone. Below: the exact rule, quick checks, many copy/paste rewrites, and ready-made examples for work, school, and casual use so you can fix sentences fast.

Quick answer

Match the verb to the grammatical subject: use is for singular subjects (The dog is) and are for plural subjects (The dogs are).

Singular subject → singular verb: The dog is hungry.
Plural subject → plural verb: The dogs are barking.
Ignore intervening phrases (along with, together with); they don't change the subject's number.

Core explanation: subject + verb = agreement

Subject-verb agreement means the verb reflects whether the subject is singular or plural. For the present form of be, use is for one and are for more than one.

Locate the grammatical subject (the doer or main noun). Words between the subject and verb often distract but don't change number.

Singular: The dog is ready.
Plural: The dogs are ready.
Intervening phrase: The dog, along with two cats, is asleep. (subject = dog → is)

Wrong: The dogs is barking outside.
Right: The dogs are barking outside.
Wrong: The dog are waiting at reception.
Right: The dog is waiting at reception.
Wrong: The dog, together with three puppies, are asleep.
Right: The dog, together with three puppies, is asleep.

Spacing and run-together mistakes

Run-together words and missing spaces can hide agreement errors. Spellcheck often misses joins like "dogis" or "dogsare."

Scan for accidental joins: the dogsare → the dogs are; The dogis → The dog is.
Check possessive spacing: The dog's collar vs The dogs' collars. Wrong spacing can hide plurality.

Wrong: The dogsare loose in the yard.
Right: The dogs are loose in the yard.
Wrong: The dogis sleeping on the mat.
Right: The dog is sleeping on the mat.
Wrong: The dog's collars are on the floor. (intended: many dogs own the collars)
Right: The dogs' collars are on the floor.

Hyphenation and compound nouns

Hyphens and compounds don't change agreement-the head noun does. Watch internal plurals and hyphenated terms.

Compound head decides number: The dog-walker is late. The dog-walkers are late.
Internal plurals: Passersby are expected (not is).
If a compound ends with a plural word, the verb is plural: Mothers-in-law are meeting.

Wrong: The dog-walkers is at the corner.
Right: The dog-walkers are at the corner.
Wrong: The mothers-in-law is joining the meeting.
Right: The mothers-in-law are joining the meeting.

Grammar edge cases: collective nouns and quantifiers

Collective nouns (team, family) can be treated as singular or plural depending on meaning. Quantifiers determine number: each/every → singular; many/several → plural.

Group-as-one: The team is ready.
Members-as-individuals: The team are arguing. (more common in British usage)
Each/every: Each dog is vaccinated. Many dogs are vaccinated.

Wrong: The team are meeting at 9:00. (if you mean the unit)
Right: The team is meeting at 9:00.
Wrong: Each dogs are required to have tags.
Right: Each dog is required to have a tag.
Wrong: There is many dogs in the shelter today.
Right: There are many dogs in the shelter today.

Test the whole sentence rather than an isolated phrase-context often reveals the correct choice. Swap in numbers or pronouns to check.

Rewrite help: quick fixes you can paste

If you spot a wrong is/are, choose one of three quick fixes: change the verb, change the noun number, or rephrase with a quantifier.

Change the verb: is → are when the subject is plural.
Change the noun: dog → dogs if you meant plural.
Rephrase: use there are or quantifiers (both, each, several) to make agreement obvious.

Rewrite:
Wrong: The dogs is blocking the corridor. →
Right: The dogs are blocking the corridor.
Rewrite:
Wrong: The dog are scheduled for training. →
Right: The dogs are scheduled for training. → Or: The dog is scheduled for training. (if one)

Memory tricks and quick tests

Use tiny substitution tests when scanning text or composing quickly.

Number substitution: Replace the subject with "one" or "two." one → is, two → are.
Pronoun swap: If "they are" fits, use are; if "he/she is" fits, use is.
S-test: If the head noun ends in s and is genuinely plural, use are (exception: news is singular).

Usage: Substitute: "One dog is" vs "Two dogs are" to pick the verb.
Usage: Swap pronoun: "They are barking" → so "The dogs are barking."
Usage: S-test: "The news is surprising" (news looks plural but is singular).

Similar mistakes to watch for

After fixing is/are, scan for demonstratives, quantifiers, and possessives that often accompany agreement errors.

This/These: This dog is friendly vs These dogs are friendly.
There is/There are: There is a dog on the porch vs There are dogs on the porch.
Possessives and apostrophes: don't use apostrophes for simple plurals (apples, not apple's).
Their/They're/There and Your/You're are common confusions that appear alongside agreement errors.

Wrong: This dogs is friendly.
Right: These dogs are friendly.
Wrong: There is many dogs in the park today.
Right: There are many dogs in the park today.
Wrong: Their are three dogs over there.
Right: There are three dogs over there.

FAQ

Is it ever correct to say "The dogs is"?

No. "The dogs is" is incorrect because "dogs" is plural and requires "are." Use "The dog is" if you mean one dog.

How do I quickly fix "The dog are"?

Decide whether you mean one or more. If plural, make the noun plural: The dogs are. If singular, change the verb: The dog is.

Do intervening phrases change agreement?

No. Phrases like "along with" or "together with" don't change the subject's number. Remove them mentally to check: "The dog, along with the cats, is asleep."

What about collective nouns like team or family?

Use a singular verb when the group acts as one (The team is ready). Use a plural verb when you emphasize individual members (The team are arguing). American English usually treats collective nouns as singular.

Any fast tools to catch these errors?

Use the one/two substitution, pronoun swap, or paste the sentence into a grammar checker. Or copy one of the corrected examples above as a template.

Need a quick check?
