Grew or Grown? The Simple Difference Most English Learners Get Wrong (2026)

Many English learners struggle with grew and grown because both words come from the verb grow. They are related to the same action, but they are used in different grammar situations.

You might hear sentences like:

• “The plant grew quickly.”
• “The plant has grown quickly.”

Both are correct, but they follow different grammar rules.

The confusion usually happens because grew is the past tense, while grown is the past participle. Once you understand this simple difference, choosing the right word becomes easy.

Quick Answer

• Grow = base form
• Grew = simple past tense
• Grown = past participle
• Use grew for actions completed in the past.
• Use grown with helping verbs such as has, have, had, was, were, be, been.

Examples

✅ The tree grew very fast last year.

✅ The tree has grown very fast this year.

❌ The tree has grew very fast.

❌ The tree grown very fast last year.

Simple Origin or Background Explanation

The verb grow is an irregular verb. Unlike regular verbs, it does not form its past tense by simply adding -ed.

For example:

• Walk → Walked
• Play → Played

But grow follows a different pattern:

Verb Form	Word
Base Verb	Grow
Past Tense	Grew
Past Participle	Grown

Because these forms look different, learners often mix them up.

The Difference Between Grew and Grown

The difference is based on grammar, not meaning.

Grew

Use it when talking about something that happened and finished in the past.

Examples:

Grown

Grown is the past participle form.
