Grew or Grown: What Is the Difference? Meaning, Rules, and

Have you ever wondered if to use grew or grown when talking about something that increased in size, developed over time, or changed? Both words come from the verb grow, but they are used in different grammatical situations. Understanding the difference between grew and grown will help you write clearer sentences and speak English more confidently.

The main difference is simple: grew is the simple past tense of grow, while grown is the past participle. Use grew when describing an action or change that happened in the past. Use grown with helping verbs such as has, have, or had.

For example, “The plant grew quickly last summer” is correct, while “The plant has grown quickly” is also correct. However, “The plant has grew quickly” is incorrect in standard English. Learning these patterns will help you avoid common grammar mistakes in schoolwork, everyday conversations, and professional writing.

Quick Answer: Grew vs. Grown

Grew is the simple past tense of grow, used for an action or change that happened in the past. Grown is the past participle, used with helping verbs such as has, have, and had, or as an adjective. For example: “The child grew taller” and “The child has grown taller.”

Why Do People Confuse Grew and Grown?

People often confuse these words because both describe growth or development and come from the same verb. Their meanings are closely related, but their grammatical roles are different.

English has many irregular verbs that do not form the past tense by simply adding -ed. The verb grow follows this pattern:

• Grow: Base form
• Grew: Simple past tense
• Grown: Past participle

The key is to look at the other words in your sentence. If you are describing a completed past action without a perfect-tense helping verb, grew is usually the right choice. If you are using has, have, or had to form a perfect tense, use grown.

Examples:

• Correct: The business grew rapidly last year.
• Correct: The business has grown rapidly.
• Incorrect: The business has grew rapidly.

What Does Grew Mean?

Grew is the simple past tense of the verb grow. It describes something that increased in size, developed, matured, or became greater in amount or degree in the past.

The word can describe physical growth, emotional development, business expansion, popularity, or changes in feelings.

Examples of Grew in Sentences

• Our family grew vegetables in the garden.
• The company grew rapidly during the 1990s.
• She grew more confident after the presentation.
• Their friendship grew stronger over time.
• The crowd grew larger as the concert began.

In each example, grew describes a change that happened in the past.

Use grew when you want to express a past change or development without using a perfect-tense construction.

For example:

• The tree grew near the river.
• His interest in science grew during school.
• The problem grew worse over time.

You can also use grew with expressions such as yesterday, last year, and when I was younger.

Example: “My interest in reading grew when I was a child.”

What Does Grown Mean?

Grown is the past participle of the verb grow. It is used with helping verbs to form perfect tenses and can also function as an adjective.

Common Mistakes With Grew and Grown

Even fluent English speakers sometimes mix up irregular verb forms. Here are common errors and their corrections.

Incorrect	Correct	Explanation
She has grew taller.	She has grown taller.	Use the past participle after has.
The plant has grew quickly.	The plant has grown quickly.	Perfect tenses require grown.
They had grew apart.	They had grown apart.	Use grown after had.
He grown older last year.	He grew older last year.	Use the simple past for a standalone past action.
The business have grew.	The business has grown.	Match the singular subject with has and use grown.
I have grow a lot.	I have grown a lot.	Use the past participle after have.

Why Is “Has Grew” Incorrect?

In standard English, has must be followed by the past participle when forming the present perfect tense. Since grown is the past participle of grow, the correct phrase is “has grown,” not “has grew.”

Similarly, use have grown and had grown.

Easy Memory Trick for Grew vs. Grown

Try this simple trick:

Grew = Past action. Grown = Has, Have, or Had.

Remember these example patterns:

• Yesterday, the plant grew.
• The plant has grown.
• The plant had grown before winter.

You can also memorize the three forms together:

Grow → Grew → Grown

Say the sequence aloud a few times and create one sentence for each form. This will help you remember the correct pattern when speaking or writing.

One important detail: grown can also be used as an adjective, as in “a grown man,” so it does not always need a helping verb.

Grew vs. Grown in American and British English

There is no standard American-versus-British spelling difference between grew and grown. Both forms are used in American English, British English, Australian English, and other major varieties of English.

The difference is grammatical, not regional.

Examples in American English:

• The company grew quickly.
• The company has grown quickly.

Examples in British English:

• The company grew quickly.
• The company has grown quickly.

The same rules apply in both varieties. Regional differences may affect vocabulary, pronunciation, or other spelling choices, but they do not change the standard past-tense and past-participle forms of grow.

Final Verdict: Is It Grew or Grown?

Both grew and grown are correct words, but they serve different grammatical purposes.

Use grew as the simple past tense of grow: “The tree grew quickly.”

Use grown as the past participle with has, have, or had: “The tree has grown quickly.” You can also use grown as an adjective: “He is a grown man.”

If you are unsure which form to choose, check whether your sentence needs a simple past verb or a past participle. This small grammar check will help you use both words correctly.

FAQs:

1. Is it grew or grown?

Both are correct, depending on the sentence. Grew is the simple past tense of grow, while grown is the past participle. Say “The plant grew” but “The plant has grown.”

2. Is “has grew” grammatically correct?

No. In standard English, use “has grown.” The present perfect tense requires has followed by the past participle, not the simple past form.

Correct: “The child has grown taller.”

Incorrect: “The child has grew taller.”

3. Is it “I grew up” or “I grown up”?

The correct expression is “I grew up.” Use grew because the sentence describes a past experience. You can also say “I have grown up” when using the present perfect, although the meaning and context may differ.

4. What is the past tense of grow?

The simple past tense of grow is grew.

Example: “The flowers grew in the garden last summer.”

The past participle is grown, as in “The flowers have grown.”

5. What is the past participle of grow?

The past participle of grow is grown.

It is used with helping verbs in perfect tenses, such as “has grown,” “have grown,” and “had grown.”

6. Can grown be used without has, have, or had?

Yes. Grown can function as an adjective or appear in other participial constructions.

Examples: “He is a grown man” and “The vegetables are grown locally.”

7. Is it “had grew” or “had grown”?

The correct form is “had grown.” The past perfect tense uses had followed by the past participle.

Example: “The tree had grown considerably before the storm.”

Remember This

• Grow: Present or base form — “Plants grow in sunlight.”
• Grew: Simple past — “The plants grew last summer.”
• Grown: Past participle — “The plants have grown.”
• Grown: Adjective — “He is a grown man.”

The most useful rule is simple: grew describes a past action, while grown is the past participle used in perfect tenses and can also describe a mature state.

Conclusion

Understanding the difference between grew and grown is an important step toward using English grammar correctly. Although both words come from the verb grow, they are not interchangeable. Use grew when describing a change that happened in the past, such as “The tree grew quickly.” Use grown when forming perfect tenses, such as “The tree has grown quickly,” or when describing maturity, as in “a grown child.”

The best way to remember these forms is to practice them in complete sentences. Learn the sequence grow, grew, grown, pay attention to helping verbs, and check the tense before choosing a word. With regular practice, you will find it easier to use these forms naturally in conversations, essays, school assignments, and everyday writing.
