Blew is the simple past tense of blow, while blown is the past participle. Use blew for a completed past action without an auxiliary verb: “The wind blew all night.” Use blown after a form of have or in a passive construction: “The wind has blown hard” or “The door was blown open.” The correct choice depends on the verb structure, not merely the time of the action.
Key Facts at a Glance
- Blow is the base form: “Birds blow air through their lungs.”
- Blew is the simple past form: “The referee blew the whistle.”
- Blown is the past participle: “The referee has blown the whistle.”
- Has, have, and had require blown, not blew, when they form a perfect tense.
- Was or were can take blown in the passive voice, but they take blowing in the past progressive: “The wind was blowing.”
- A modal verb such as could, should, or might takes the base form blow: “The valve might blow.”
Is Blew or Blown the Correct Past Tense of Blow?
Blew is the correct simple past tense of blow, but blown is not another simple past option. Blown is the past participle, so it normally appears with an auxiliary verb such as has, have, had, is, was, or been. Compare “The storm blew the sign down” with “The storm has blown the sign down.”
English has many irregular verbs whose past tense and past participle differ. The pattern is:
| Verb form | Grammatical name | Example |
|---|---|---|
| blow | Base form | “Please blow out the candle.” |
| blew | Simple past | “She blew out the candle.” |
| blown | Past participle | “She has blown out the candle.” |
| blowing | Present participle | “She is blowing out the candle.” |
The same distinction appears in literal and figurative uses. A person blew a whistle, a tire blew on the highway, and an investor blew an opportunity. The corresponding perfect forms are “has blown a whistle,” “has blown a tire,” and “has blown an opportunity.”
What Does Blew Mean?
Blew means that the subject completed an action in the past. The word can describe moving air, forcing air into something, producing a sound with air, exploding, wasting something, or failing badly.
Examples include:
- “A cold wind blew through the window.”
- “Maya blew up the balloon.”
- “The referee blew the whistle.”
- “The fuse blew during the storm.”
- “I blew my chance to apply.”
- “The mechanic said the engine blew.”
A sentence with blew may include a time expression such as yesterday, last night, or two hours ago, but it does not require one. “The candle blew out” is grammatical when the surrounding context already establishes the past.
What Does Blown Mean?
Blown is the past participle of blow, and it usually needs another verb to complete the verb phrase. Perfect constructions use has blown, have blown, or had blown, while passive constructions use forms such as was blown, were blown, or had been blown.
Examples include:
- “The storm has blown the roof tiles loose.”
- “The fuse had blown before the technician arrived.”
- “The papers were blown across the pavement.”
- “The candle has been blown out.”
- “The budget was blown by emergency repairs.”
In some contexts, blown functions as an adjective rather than as part of a complete verb phrase. “A blown fuse” describes a fuse that has failed. The adjective still relates to the past participle, but the sentence does not use blown as a simple past verb.
How Do You Choose Between Blew and Blown?
Use blew when the subject directly performed a completed past action, and use blown when an auxiliary verb requires a past participle. First identify the auxiliary verb, then determine whether the sentence expresses perfect tense, passive voice, or a different construction such as the progressive.
Use this decision process:
- Find the main verb. Look for the action involving air, sound, inflation, failure, or figurative loss.
- Check the verb before the blank. Has, have, and had normally require blown.
- Check the voice. “Was blown” is passive, while “blew” is active.
- Check for a progressive form. “Was blowing” describes an action in progress and does not use blown.
- Check for a modal or infinitive. Could blow and to blow use the base form.
| Sentence pattern | Correct form | Example |
|---|---|---|
| Subject + simple past | blew | “The gale blew down the fence.” |
| Has/have + participle | blown | “The gale has blown down the fence.” |
| Had + participle | blown | “The gale had blown down the fence.” |
| Was/were + passive participle | blown | “The fence was blown down.” |
| Was/were + progressive participle | blowing | “The gale was blowing hard.” |
| Modal + base form | blow | “The gale could blow down the fence.” |
The most reliable editing rule is structural rather than semantic. Ask whether the sentence has already supplied an auxiliary that controls the form. The action may have happened yesterday in both “The wind blew” and “The wind has blown,” but the grammar differs.
When Does Blown Follow Has, Have, or Had?
Blown follows has, have, or had when those auxiliaries form a perfect tense. Use has blown or have blown for an action connected to the present, and use had blown for an earlier action viewed from a past reference point.
| Perfect construction | Time relationship | Correct example |
|---|---|---|
| has blown | One subject, present relevance | “The wind has blown the leaves away.” |
| have blown | Plural subject or I/you | “The storms have blown in from the coast.” |
| had blown | Earlier than another past event | “The fuse had blown before dawn.” |
| has been blown | Present perfect passive | “The candle has been blown out.” |
| had been blown | Past perfect passive | “The papers had been blown away.” |
The sentence “The wind has blew all morning” is incorrect because has requires the past participle blown. The corrected version is “The wind has blown all morning.” The sentence “The wind blew all morning” is also correct, but it uses the simple past and does not contain has.
A common misconception is that a completed action must always use blew. Perfect tenses can describe completed actions too. The difference is the grammatical relationship to another time, not simply whether the action ended.
Does Was Always Require Blown?
No. Was requires blown only when the sentence is passive or uses a participial adjective; was blowing is correct for a past progressive action. The auxiliary must be interpreted with the word that follows it.
Compare these constructions:
- Passive: “The door was blown open by the storm.”
- Progressive: “The wind was blowing through the doorway.”
- Description: “The fuse was blown.”
- Simple past: “The storm blew the door open.”
In “The door was blown open,” the door receives the action, so the sentence uses passive voice. In “The wind was blowing,” the wind performs an action that was in progress, so the sentence uses the present participle blowing. Replacing blowing with blown would change the grammar and usually make the sentence incorrect.
| Auxiliary structure | Meaning | Example |
|---|---|---|
| was blown | Passive or resulting state | “The sign was blown over.” |
| were blown | Passive, plural subject | “The leaves were blown away.” |
| was blowing | Past action in progress | “The fan was blowing cold air.” |
| had been blown | Earlier passive event | “The gate had been blown open.” |
This distinction is the most important refinement missing from the shortcut “was means blown.” The shortcut works for passive examples, but it fails for progressive forms.
What Form Follows a Modal Verb or To?
A modal verb or the infinitive marker to takes the base form blow, not blew or blown. Write “might blow,” “should blow,” and “to blow,” even when the sentence refers to a future possibility or a past decision.
Correct examples include:
- “The pressure could blow the seal.”
- “The technician should blow dust from the filter.”
- “The pipe might blow if the valve sticks.”
- “I wanted to blow out the candle.”
- “The instructions tell users to blow into the tube.”
For a past event after a modal, English often uses a perfect modal: might have blown, could have blown, or should have blown. The participle follows have:
- “The fuse might have blown overnight.”
- “The wind could have blown the papers away.”
- “The operator should have blown the whistle sooner.”
“Could blew” and “could blown” are incorrect because could takes the base form directly. “Could have blew” is also incorrect because have requires blown.
How Do Tense and Voice Change the Meaning?
Simple past focuses on the completed action, while perfect and passive structures add a time relationship or shift attention to the affected object. Choosing blew or blown therefore changes both grammatical form and the sentence’s emphasis.
| Form | Voice or tense | Example | Main focus |
|---|---|---|---|
| blew | Simple past, active | “The child blew bubbles.” | Child’s completed action |
| has blown | Present perfect, active | “The child has blown bubbles.” | Past action with present relevance |
| had blown | Past perfect, active | “The child had blown bubbles.” | Earlier past action |
| was blown | Simple past, passive | “The bubble was blown by the child.” | Bubble receiving action |
| was blowing | Past progressive, active | “The child was blowing bubbles.” | Action in progress |
| has been blown | Present perfect, passive | “The bubble has been blown.” | Completed result |
Active voice is often shorter and clearer when the actor matters. “The storm blew the roof tiles away” identifies the cause immediately. Passive voice is useful when the affected object matters more or the actor is unknown: “The roof tiles were blown away during the night.”
How Are Blew and Blown Used in Phrasal Verbs?
Phrasal verbs keep the same grammatical distinction: blew is the simple past form, and blown follows perfect or passive auxiliaries. The particle changes the meaning, but it does not change the underlying verb forms.
| Base phrasal verb | Simple past | Past participle | Meaning |
|---|---|---|---|
| blow out | blew out | blown out | Extinguish or burst |
| blow up | blew up | blown up | Explode or enlarge |
| blow away | blew away | blown away | Move by wind or impress |
| blow over | blew over | blown over | Pass or fall because of wind |
| blow off | blew off | blown off | Detach or ignore |
Examples:
- “The wind blew out the lantern.”
- “The wind has blown out the lantern.”
- “The old tire blew up on the motorway.”
- “The tire had blown up after the impact.”
- “The dispute blew over by Friday.”
- “The dispute has blown over.”
Some phrasal verbs have figurative meanings. “I blew off the meeting” means “I skipped or ignored the meeting,” while “The meeting has blown over” would mean the meeting itself passed, which is unlikely. Context controls the meaning, but auxiliary selection still controls the verb form.
Are Blew and Blown Pronounced Differently?
Blew and blue are pronounced alike, while blown has an additional final consonant sound. In standard English pronunciation, blew is commonly /bluː/, and blown is commonly /bloʊn/, although exact vowel quality varies by accent.
The homophone blue creates a separate spelling problem:
- “The sailor blew the whistle.”
- “The sailor wore a blue jacket.”
- “The sailor has blown the whistle.”
Pronunciation cannot reliably identify the written form because blew and blue sound the same. Writers must use sentence meaning and grammar. A proofreading tool may detect “blew” versus “blown,” but it may not detect every context error involving the homophone blue.
What Are the Most Common Errors?
The most common mistakes are pairing blew with a perfect-tense auxiliary, using blown as a standalone simple past verb, and confusing passive was blown with progressive was blowing. Each error can be corrected by identifying the complete verb phrase.
Mistake 1: Has Blew
Incorrect: “The wind has blew the papers away.”
Correct: “The wind has blown the papers away.”
Reason: Has forms the present perfect and requires the past participle blown.
Mistake 2: I Blown
Incorrect: “Yesterday, I blown out the candles.”
Correct: “Yesterday, I blew out the candles.”
Reason: The sentence uses simple past without an auxiliary. The subject directly performs the completed action.
Mistake 3: Was Blowing Replaced With Was Blown
Incorrect for an ongoing action: “The fan was blown cold air.”
Correct: “The fan was blowing cold air.”
Reason: Was blowing is progressive. Was blown would normally mean that someone or something blew the fan itself, or that the fan was described as damaged.
Mistake 4: Could Blew
Incorrect: “The pressure could blew the cap off.”
Correct: “The pressure could blow the cap off.”
Reason: Modal verbs take the base form.
Mistake 5: To Blown
Incorrect: “She tried to blown up the balloon.”
Correct: “She tried to blow up the balloon.”
Reason: The infinitive marker to takes the base form.
Can Blown Stand Alone?
Blown can appear without an immediately adjacent auxiliary when it functions as an adjective or appears in a reduced phrase, but it cannot normally serve as the standalone simple past verb of blow. “The fuse is blown” is grammatical because is supports a passive or adjectival construction, while “The fuse blown yesterday” is not a complete standard sentence.
Compare:
- Complete simple past: “The fuse blew yesterday.”
- Complete passive: “The fuse was blown during testing.”
- Complete perfect: “The fuse has blown.”
- Adjectival phrase: “Replace the blown fuse.”
- Incomplete clause: “The fuse blown yesterday.”
A reduced clause can use blown in formal writing when another structure supplies the connection: “The fuse, blown during testing, was replaced.” Here, blown during testing modifies fuse; it is not the sentence’s finite verb.
Do Blew and Blown Have Different Meanings?
Blew and blown do not have separate core dictionary meanings, but their grammatical roles can alter the meaning and emphasis of a sentence. Both forms can describe air movement, inflation, explosions, sounds, failure, waste, or figurative mistakes.
| Context | Blew example | Blown example |
|---|---|---|
| Wind | “The wind blew the leaves away.” | “The leaves were blown away.” |
| Electrical failure | “The fuse blew.” | “The fuse has blown.” |
| Money | “He blew his paycheck.” | “He has blown his savings.” |
| Opportunity | “She blew her chance.” | “She had blown her chance.” |
| Explosion | “The engine blew.” | “The engine had blown.” |
| Extinguishing | “I blew out the candle.” | “The candle was blown out.” |
The phrase “the engine is blown” can also mean the engine is severely damaged, especially in informal automotive English. That sentence uses blown as a description of condition, not necessarily a passive event performed by a named person.
Which Form Should You Use in Common Situations?
Use blew for a finished past event in ordinary narration, and use blown when the sentence contains a perfect or passive construction. The following examples cover the situations most often encountered in editing, schoolwork, technical reports, and conversation.
| Situation | Preferred form | Example |
|---|---|---|
| Action yesterday | blew | “The wind blew yesterday.” |
| Action connected to now | has blown | “The wind has blown debris onto the road.” |
| Earlier past event | had blown | “The storm had blown over by noon.” |
| Unknown or unimportant actor | was blown | “The sign was blown into the ditch.” |
| Ongoing past action | was blowing | “The wind was blowing at midnight.” |
| Possibility | might blow | “The valve might blow under pressure.” |
| Completed action after a modal | might have blown | “The valve might have blown overnight.” |
| Noun modifier | blown | “Inspect the blown fuse.” |
Technical writers should distinguish a cause from a condition. “The fuse blew because of an overload” reports an event and suggests a causal investigation. “The fuse is blown” reports the current condition but does not establish when or why the failure occurred.
What Is the Fastest Editing Test?
Replace the disputed form with another irregular verb such as go, went, or gone. If the sentence needs gone, use blown; if it needs went, use blew; if it needs the infinitive, use blow.
Apply the substitution:
- “The wind ___ through the valley.”
“The wind went through the valley.” Therefore, use blew. - “The wind has ___ through the valley.”
“The wind has gone through the valley.” Therefore, use blown. - “The wind might ___ through the valley.”
“The wind might go through the valley.” Therefore, use blow. - “The papers were ___ across the floor.”
“The papers were gone across the floor” does not work semantically, but the passive pattern signals blown, not blew.
A four-question proofreading routine works well:
- Is the sentence describing a completed past action by the subject?
- Does has, have, or had appear before the verb?
- Is the subject receiving the action in a passive construction?
- Is the verb after was describing an ongoing action?
Answers produce the following choices: simple past equals blew, perfect or passive equals blown, progressive equals blowing, and modal or infinitive equals blow.
FAQ
Is “The Wind Has Blew” Ever Correct?
No. “The wind has blew” is incorrect in standard English because has requires the past participle blown. Write “The wind has blown.” If you want simple past, remove has and write “The wind blew.” The two versions differ in tense and time framing, but only the second uses blew.
Is “The Fuse Has Blew” Correct?
No. The correct sentence is “The fuse has blown.” The phrase uses the present perfect, formed with has plus the past participle. “The fuse blew” is also correct when reporting a completed past event without an auxiliary. “The fuse is blown” describes its current failed condition.
Is “The Balloon Was Blown Up” Grammatical?
Yes. “The balloon was blown up” is grammatical passive voice, meaning someone or something inflated the balloon. “The balloon blew up” means the balloon burst or exploded. “The balloon was blowing up” normally describes an ongoing inflation process and requires a context that identifies who or what was inflating it.
What Is the Past Tense of Blow Up?
The simple past of blow up is blew up, and its past participle is blown up. Write “The tire blew up on the road” for a completed past event. Write “The tire has blown up” for the present perfect, or “The tire was blown up” when the sentence uses passive voice.
What Is the Past Tense of Blow Out?
The simple past is blew out, while the past participle is blown out. Write “She blew out the candles” for a completed action. Write “She has blown out the candles” for the present perfect. In “The candle was blown out,” the candle receives the action in a passive construction.
Is “Blown” an Adjective?
Yes. Blown can function as an adjective in phrases such as “a blown fuse,” “a blown engine,” or “a blown tire.” It can also function as a past participle in “The fuse has blown” or “The tire was blown out.” The surrounding words determine whether the form belongs to a verb phrase or modifies a noun.
The Bottom Line
Blew is the simple past tense of blow, and blown is the past participle. Use blew in “The wind blew hard yesterday.” Use blown after has, have, or had, as in “The wind has blown hard,” and in passive constructions such as “The door was blown open.” Remember that was blowing, could blow, and to blow use different forms because they express progressive, modal, and infinitive structures. When deciding between blew or blown which is the correct past tense of blow, choose blew for simple past and blown for perfect or passive grammar.
