Common Mistakes with the Verb ‘grow’

The verb grow is irregular, and its forms—grow (present), grew (past tense), and grown (past participle)—are frequently confused. The most common mistake is using grew where grown is needed (e.g., “I have grew tomatoes” instead of “I have grown tomatoes”) or using grown as a simple past tense (e.g., “I grown up in Texas” instead of “I grew up in Texas”). This guide will help you use each form correctly in writing, conversation, and email.

Quick Answer: The Three Forms of ‘grow’

• Present: grow (used for current actions or general truths: “Plants grow toward the sun.”)
• Past Tense: grew (used for completed actions in the past: “The tree grew very tall last year.”)
• Past Participle: grown (used with auxiliary verbs like have, has, had, or be: “She has grown a lot since I last saw her.”)

Understanding the Forms in Context

Present Tense: grow

Use grow for things happening now or always true. It works in both formal and informal settings.

• Formal/Email: “Our company continues to grow its international presence.”
• Informal/Conversation: “My hair grows so fast in the summer.”

Past Tense: grew

Use grew for a finished action in the past. No helper verb is needed.

• Formal/Email: “The project grew beyond our initial expectations.”
• Informal/Conversation: “I grew up in a small town.”

Past Participle: grown

Use grown with have, has, had, or forms of be (e.g., is grown, was grown). This is where most errors happen.

• Formal/Email: “The company has grown its revenue by 20% this quarter.”
• Informal/Conversation: “I have grown tired of waiting.”

Common Mistakes

Mistake 1: Using grew with a helper verb

Incorrect: “I have grew tired of this routine.”
Correct: “I have grown tired of this routine.”
Explanation: After have, has, or had, you must use the past participle grown, not the past tense grew.

Mistake 2: Using grown as a simple past tense

Incorrect: “The child grown three inches last month.”
Correct: “The child grew three inches last month.”
Explanation: For a completed action in the past without a helper verb, use grew.

Mistake 3: Confusing grow and grew in present perfect

Incorrect: “The company has grew rapidly.”
Correct: “The company has grown rapidly.”
Explanation: Present perfect always requires the past participle.

Mistake 4: Using grow for past events

Incorrect: “Yesterday, I grow tired of waiting.”
Correct: “Yesterday, I grew tired of waiting.”
Explanation: Past time markers like yesterday require the past tense.

Better Alternatives and When to Use Them

Sometimes grow is not the best word. Here are alternatives for different contexts.

• Increase (formal, business): Use instead of grow for numbers or statistics. “Sales increased by 15%.” (More formal than “Sales grew.”)
• Expand (business, physical size): “The company expanded its operations.” (Better than “grew” when talking about scope.)
• Develop (skills, abilities): “She developed her public speaking skills.” (More precise than “grew” for personal improvement.)
• Mature (emotional or physical growth): “He matured a lot after college.” (Better than “grew up” for emotional development.)
• Raise (children, plants, animals): “They raised three children.” (Use raise instead of grow when talking about caring for living things.)

When to use grow: Stick with grow for natural processes (plants, hair, nails), general increase, and informal conversation. Use the alternatives for more formal or specific writing.

FAQ: Common Questions About ‘grow’

1. Is it “I grew up” or “I have grown up”?

Both are correct but used differently. “I grew up in Chicago” (simple past, finished action) refers to a completed childhood. “I have grown up” (present perfect) emphasizes the current state of being an adult, often used in phrases like “I have grown up a lot since then.”

2. Can I use “grow” for business growth?

Yes, but it is informal. In business emails, increase or expand sounds more professional. For example, “Our revenue grew by 10%” is acceptable in casual reports, but “Our revenue increased by 10%” is better for formal documents.

3. What is the difference between “grow” and “raise”?

Grow is used for plants or things that develop naturally (e.g., “I grow tomatoes”). Raise is used for animals or children (e.g., “I raise chickens” or “She raised her kids alone”). For plants, both are possible, but grow is more common.

4. Is “grown” ever used without a helper verb?

Yes, but only as an adjective. For example, “a grown man” or “fully grown plants.” In these cases, grown describes a state, not an action.

Final Tips for Using ‘grow’ Correctly

• If you see have, has, or had nearby, use grown.
• If the action is finished and in the past with no helper verb, use grew.
• For present actions or general truths, use grow.
• In formal writing, consider alternatives like increase or expand for precision.
• Practice with the mini exercise above until the forms feel natural.
