Let’s look at the difference step by step and make it easy to remember.

A Simple Background of the Word “Blow”

The word blow has been part of English for a very long time. Like many common English verbs, it has an irregular past form. This means we do not simply add -ed to make the past tense.

For example:

• Walk → Walked → Walked
• Play → Played → Played

These are regular verbs. But blow is different:

• Blow → Blew → Blown

This is why learners sometimes make mistakes. English has many irregular verbs, and their forms need to be learned individually.

The verb blow can also have several meanings. It can describe:

• Wind moving through the air
• A person pushing air from their mouth
• Something exploding or being destroyed
• Missing or wasting an opportunity
• Playing a musical instrument

The meaning may change, but the grammar rule for blew and blown stays the same.

Understanding the Difference Between Blew and Blown

What Does “Blew” Mean?

Blew is the simple past tense of blow. Use it when an action happened and finished at a particular time in the past.

Examples:

• The wind blew very hard last night.
• She blew out the candles.
• He blew into his hands to keep them warm.
• The referee blew the whistle.
• Our plans blew up because of the bad weather.

In these sentences, blew tells us about something that happened in the past.

You will often see words like these with blew:

• yesterday
• last night
• last week
• earlier
• two days ago
• when I was younger

For example:

Yesterday, the wind blew for hours.

The action happened in the past, so blew is the correct choice.

What Does “Blown” Mean?

Blown is the past participle of blow. A past participle usually needs a helping verb.

Common helping verbs include:

Examples:

Notice that blown does not usually stand alone as the main verb.

Which One Should You Use and When?

The easiest way to choose between blew and blown is to look at the words around it.

Use “Blew” for a Simple Past Action

Choose blew when you are simply saying what happened in the past.

Examples:

• The strong wind blew my hat away.
• I blew the dust off the table.
• She blew a kiss before leaving.
• The coach blew the whistle.
• He blew his chance to win the game.

These actions are presented as completed events.

Choose blown when the action connects to another time or event.

Examples:

• The wind has blown all afternoon.
• I have blown up the balloons.
• She had blown out the candles before we arrived.

The helping verb is important here.

Have + blown
Has + blown
Had + blown

Never use blew after has, have, or had.

Incorrect: She has blew the whistle.
Correct: She has blown the whistle.

Use “Blown” in Passive Sentences

Blown is also used in passive sentences.

Here, something receives the action.

Common Mistakes People Make

Learning common mistakes can help you avoid them.

Mistake 1: Using “Blown” Alone as the Past Tense

Some learners write:

Incorrect: The wind blown yesterday.

This is wrong because blown is not normally used alone as the simple past tense.

Say:

Correct: The wind blew yesterday.

Mistake 2: Using “Blew” After “Have” or “Has”

This is a very common mistake.

Incorrect: He has blew his chance.

The correct past participle is blown.

Correct: He has blown his chance.

Mistake 3: Forgetting That “Blow” Has Different Meanings

The grammar form stays the same even when the meaning changes.

Wind: The wind blew all night.
Candles: She blew out the candles.
Opportunity: He blew his chance.
Explosion: The building was blown apart.

Do not choose the verb form based only on the meaning. Look at the sentence structure too.

Mistake 4: Thinking “Blew” and “Blown” Can Always Replace Each Other

They cannot.

Compare:

• She blew the whistle. ✅
• She has blown the whistle. ✅

But:

• She blown the whistle. ❌
• She has blew the whistle. ❌

The helping verb changes which form you need.
