When I’m writing this, I often think about how people contract phrasees in English. I’m commonly used informally to shorten “I am” before a noun, like “I’m a man”. In contrast, I am is used more formally, often emphasizing the noun in a sentence. Examples of this include “A man, I am” or “I am a man”. These rules help see how a contraction can change the flow of your speaking or writing.
We’ll start by using an example: when speaking, I’m is the common form because it saves time and doesn’t require two syllables to pronounce. You can write it informally, but formally, I am fits better. Observing this action in daily communication makes English feel natural and helps you see the difference without overthinking.
Why “Is” vs. “Are” Still Confuses People
Many people confuse “is” and “are” because English has exceptions that defy simple rules. For example, collective nouns like team or staff can take either verb depending on context. Similarly, phrases like “a number of” versus “the number of” change verb forms. Misusing these words can lead to grammatical errors, especially in academic papers or professional documents.
Understanding the difference isn’t just about grammar—it’s about clarity. Using the right form shows that your writing is precise, confident, and easy to read.
Core Grammar Rule: Singular vs. Plural Verbs
The fundamental rule is straightforward: the verb must agree with the subject. Singular nouns pair with is, while plural nouns pair with are.
| Subject Type | Example | Correct Verb |
| Singular noun | The book | is on the table |
| Plural noun | The books | are on the table |
| Singular pronoun | She | is happy |
| Plural pronoun | They | are happy |
This table illustrates the most basic form of subject-verb agreement, but many nuances exist, especially with collective nouns and tricky phrases.
Using “Is” Correctly
Singular Nouns That Always Take Is
When your subject is singular, is is the correct choice.
Examples:
- The student is studying for the exam.
- The computer is turned off.
- The teacher is preparing the lesson plan.
Notice how the verb always matches the single subject.
Is with Singular Pronouns
Singular pronouns like he, she, it, this, that always pair with is.
Examples:
- He is responsible for the project.
- She is reading the new report.
- It is important to submit the form on time.
This rule also applies in professional writing. Using is with singular pronouns maintains formal accuracy.
Is with Singular Collective Nouns
Collective nouns refer to a group acting as a single unit. In this case, is is correct.
Examples:
- The team is winning the championship.
- The staff is attending the meeting.
- The committee is reviewing the proposals.
Think of the group as one entity rather than multiple individuals.
Singular Ideas Treated as One
Some nouns appear plural but are treated as singular, such as titles, amounts, or names of countries.
Examples:
- Ten dollars is enough for lunch.
- The United States is a large country.
- Mathematics is essential for engineering students.
These exceptions often confuse learners, but identifying the actual singular subject helps.
Using “Are” Correctly
Plural Nouns That Always Take Are
Plural subjects require are.
Examples:
- The students are preparing for finals.
- The books are on the shelf.
- The ideas are innovative and practical.
Using are ensures that your sentence matches the plural subject and sounds natural.
Are with Plural Pronouns
Plural pronouns like we, you (plural), they, these, those pair with are.
Examples:
- We are excited about the trip.
- They are responsible for the project.
- These are important documents.
These forms are especially common in classrooms and workplaces.
Collective Nouns Treated as Plural
When a group acts as individuals, are is appropriate.
Examples:
- The team are arguing over their strategies.
- The staff are submitting individual reports.
- The committee are divided on the decision.
Here, the verb matches the members of the group rather than the group itself.
Plural Compound Subjects
Subjects joined by and always take are, even if each part seems singular.
Examples:
- The teacher and student are discussing the syllabus.
- My mom and dad are attending the conference.
This rule is simple but essential for clear writing.
Special Cases That Confuse English Learners
Mass Nouns (Uncountable Nouns)
Mass nouns represent something that cannot be counted individually. They always take is.
Examples:
- Water is essential for life.
- Furniture is expensive in this store.
- Advice is often ignored by students.
Even though these nouns might seem plural, the singular verb is correct.
Subjects That Come After the Verb
Sometimes the subject comes after the verb, especially in inverted sentences.
Examples:
- There is a student waiting outside.
- There are many teachers attending the seminar.
Identifying the actual subject after the verb is key to choosing the right form.
Nouns That Change Meaning Depending on Context
Certain nouns like politics, news, mathematics, statistics can be singular or plural.
Examples:
- Politics is complicated in the modern world.
- Statistics are useful for analyzing trends.
Understanding context prevents mistakes in academic and professional writing.
“There Is” vs. “There Are”: The Rule + Real Application
How to Choose Based on the Real Subject
The verb agrees with the noun following “there.”
Examples:
- There is a new student in class.
- There are five students in the lab.
When “There’s” Is Acceptable
In spoken English, contractions are common, but formal writing requires the full form.
Examples:
- Spoken: There’s many students here.
- Correct formal: There are many students here.
Common Errors Americans Make
- Incorrect: There’s many reasons for this decision.
- Corrected: There are many reasons for this decision.
Difficult Phrases That Require Extra Attention
“A Number Of” vs. “The Number Of”
| Phrase | Correct Verb | Example |
| A number of | are | A number of students are absent today. |
| The number of | is | The number of students is rising. |
Fractions and Percentages
- 50% of the class is late.
- 50% of the students are late.
Quantifiers and Expressions
