If something smells terrible, you might say, “It stinks.” But what should you say when the bad smell happened yesterday? Is it “It stank” or “It stunk”?
That is where stink vs stank vs stunk becomes confusing.
All three words come from the same irregular verb, stink, but they do not normally serve the same grammatical purpose.
Stink is the base form and present-tense form, while stank and stunk are forms used for past time and past participles. The tricky part is that stink has two accepted past-tense forms: stank and stunk.
So, unlike many word comparisons, there is no simple “right word” and “wrong word” here.
The good news is that the pattern is easy once you see how English uses these forms.
This guide explains stink vs stank vs stunk in plain English, including grammar, pronunciation, tense, examples, common mistakes, formal and informal usage, American and British English, and the easiest way to remember which form to use.
Quick Answer
Stink is the base/present form: “These shoes stink.”
Stank is a simple past form: “The shoes stank yesterday.”
Stunk is commonly used as a past participle after have, has, or had: “The shoes have stunk for days.” It is also used as a past-tense form in modern English, especially in informal American English.
Quick rule: stink → stank/stunk → stunk.

The simplest pattern
Think of the verb this way:
Present: stink
Past: stank / stunk
Past participle: stunk
For traditional grammar purposes, stank is the clearest simple-past form, while stunk is the standard past participle.
However, real English usage is slightly more flexible. Many speakers, particularly in American English, use stunk as the simple past too.
What Does “Stink” Mean?
Stink means to have a very unpleasant smell or to produce a very unpleasant odor.
It can be used as a verb and as a noun.
Stink as a verb
As a verb, stink describes something that smells very bad.
Examples:
- “The trash stinks.”
- “Your shoes stink.”
- “Something is starting to stink.”
- “This room really stinks.”
In these sentences, the smell exists now or is generally true.
Stink as a noun
Stink can also be a noun meaning a very unpleasant smell.
For example:
- “There was a terrible stink in the garage.”
- “I noticed a strange stink coming from the refrigerator.”
As a noun, stink does not change to stank or stunk.
You do not normally say:
“There was a terrible stank in the kitchen.”
The standard noun is stink.
Stink in figurative English
English speakers also use stink figuratively.
For example:
- “That deal stinks.”
- “The whole situation stinks.”
- “This movie stinks.”
Here, stink does not literally mean “smell bad.” It can mean be very unpleasant, bad, unfair, or disappointing.
The expression “That stinks!” is also common in everyday conversation when someone wants to say that something is unfortunate or disappointing.
Tip: “Stink” is much more versatile than simply talking about odors. Context determines whether the meaning is literal or figurative.
What Does “Stank” Mean?
Stank is a past-tense form of the irregular verb stink.
It normally describes something that smelled bad at a particular time in the past.
Stank in the simple past
Consider:
“The refrigerator stank yesterday.”
The bad smell existed in the past. The sentence describes a completed or clearly past situation.
More examples:
- “The fish stank after sitting outside.”
- “His old sneakers stank.”
- “The basement stank after the flood.”
- “The garbage stank in the summer heat.”
In each example, stank functions as the main verb.
Why is “stank” different from “stunk”?
English verbs often have different forms for different grammatical jobs.
For example:
- sing → sang → sung
- drink → drank → drunk
- begin → began → begun
- stink → stank → stunk
This pattern makes stank easier to understand.
Compare:
“The dog stank.”
with:
“The dog had stunk for several days.”
The first sentence uses simple past.
The second uses the past participle after had.
Is “stank” correct?
Yes.
Stank is a correct English word and a standard past-tense form of stink.
It is especially useful when you want to make the simple past unmistakably clear.
Quick rule: If you are describing a bad smell that happened in the past and you are using a simple past sentence, stank is a safe and traditional choice.
What Does “Stunk” Mean?
Stunk is the past participle of stink.
It is most clearly used with auxiliary verbs such as has, have, or had.
Examples:
- “The room has stunk all morning.”
- “The refrigerator has stunk for days.”
- “The garbage had stunk before we found it.”
- “Those shoes have stunk since last summer.”
Here, stunk does not stand alone. It works with another verb.
Stunk with “has”
“The kitchen has stunk all day.”
The action or condition began earlier and is connected to the present.
Stunk with “have”
“Those shoes have stunk since Monday.”
The plural subject shoes takes have.
Stunk with “had”
“The basement had stunk for weeks before we cleaned it.”
This is the past perfect.
The smelling happened before another event in the past.
Can “stunk” be used without “have”?
Yes.
This is where English usage becomes interesting.
Many speakers use stunk as a simple past form:
“The place stunk.”
This usage is widespread, especially in informal American English.
Traditional grammar references often present stank as the simple past and stunk as the past participle. However, stunk as a simple past form is established in actual modern usage and should not automatically be treated as a spelling or grammar mistake.
For careful formal writing, stank is often the cleaner choice for simple past.
Stink vs Stank vs Stunk: The Key Difference
The biggest difference is grammatical rather than semantic.
All three words relate to the same basic idea: having or producing a bad smell.
The form changes according to how the verb functions in the sentence.
1. Stink = present or base form
Use stink for present situations, general facts, commands, and after modal verbs or infinitives.
Examples:
- “The socks stink.”
- “I think something will stink.”
- “These shoes might stink.”
- “Don’t let the food stink up the refrigerator.”
2. Stank = simple past
Use stank to describe a past situation.
Examples:
- “The kitchen stank yesterday.”
- “The garbage stank after three days in the heat.”
- “The drain stank after the storm.”
3. Stunk = past participle
Use stunk after have, has, or had in perfect constructions.
Examples:
- “The kitchen has stunk all day.”
- “The garbage had stunk for hours.”
- “Those shoes have stunk since Friday.”
4. Stunk = also used as simple past
In everyday speech, you may hear:
“The bathroom stunk.”
This is common and understandable English.
It is not necessary to “correct” every speaker who uses stunk this way. Language changes through real usage, and stunk has a long history of use as a past form.
Grammar: Is “Stink” an Irregular Verb?
Yes.
Stink is an irregular verb, which means it does not form its past tense simply by adding -ed.
You cannot normally form its standard past tense by writing:
“stinked”
Instead, the traditional verb forms are:
| Form | Word |
|---|---|
| Base form | stink |
| Third-person singular | stinks |
| Simple past | stank / stunk |
| Past participle | stunk |
| Present participle | stinking |
Present tense
“The trash stinks.”
Because trash is singular, the third-person singular form is stinks.
Past tense
“The trash stank.”
No auxiliary verb is needed.
Present perfect
“The trash has stunk for two days.”
Here, has is the auxiliary verb and stunk is the past participle.
Past perfect
“The trash had stunk before anyone noticed.”
Again, stunk is the past participle.
Progressive form
“The trash is stinking.”
The -ing form is stinking, not stinkking.
Is “Stinked” Correct?
Usually, no, if you mean the past tense of the verb stink.
For the ordinary sense of “have a bad smell,” standard English uses stank and stunk, not stinked.
Incorrect in standard usage:
“The garbage stinked yesterday.”
Better:
“The garbage stank yesterday.”
Or, in a common informal construction:
“The garbage stunk yesterday.”
However, English contains other meanings and specialized uses of words, so context can matter. But if you are simply describing a bad smell, stinked is not the normal past form.
Warning: If you are writing an essay, business document, or other edited material, avoid stinked when you mean “smelled very bad.”
Stank vs Stunk: Which One Is Correct?
Both stank and stunk can occur in modern English, but their traditional grammatical roles are different.
Traditional distinction
The clearest traditional pattern is:
stank = simple past
stunk = past participle
For example:
“The garbage stank yesterday.”
“The garbage has stunk for days.”
This distinction is especially useful in formal or carefully edited writing.
Modern usage
In everyday speech, stunk is also frequently used as a simple past form:
“That restaurant stunk.”
“His car stunk.”
“The room stunk.”
This is especially common in American English.
Therefore, saying that stunk is always wrong in the simple past would give learners an unnecessarily rigid picture of actual English.
Which should learners choose?
If you want the safest distinction for formal writing, use:
stank for simple past.
stunk after have, has, or had.
That gives you a simple system that is grammatically clear and widely accepted.
20+ Real-Life Examples of Stink, Stank, and Stunk
The best way to understand these forms is to see them in natural contexts.
Everyday conversation
- “Something stinks in the kitchen.”
Present situation. - “These socks stink.”
Present condition. - “The garage stank after the storm.”
Past situation. - “Your backpack stinks!”
Present situation. - “The bathroom stunk yesterday.”
Informal simple past.
Text messages
- “The fridge stinks. Check the leftovers.”
- “The car stank after we left the wet clothes inside.”
- “That old gym bag has stunk for a week.”
- “Something in my room stinks 😂.”
School writing
- “The garbage stank because it had been left outside for several days.”
- “The laboratory smelled unusual, but it did not stink.”
- “The students noticed that the drain had stunk before the maintenance team arrived.”
Business and professional communication
- “The storage area has stunk since the ventilation system stopped working.”
- “Employees reported that the waste container stank after the weekend.”
- “The office began to stink after the air-conditioning unit malfunctioned.”
In a professional setting, smelled unpleasant or had an unpleasant odor may sound more neutral than stink.
Academic writing
- “The researchers observed an unpleasant odor near the sample.”
Academic writing usually avoids casual expressions such as “the sample stunk” unless the informal wording is relevant to the subject being discussed.
Social media
- “My running shoes absolutely stink after today’s workout.”
- “That old apartment stank when we first moved in.”
- “The whole place has stunk since the pipes broke.”
Figurative usage
- “That excuse stinks.”
Here, stink means “seems bad, dishonest, or suspicious,” not literally “smells bad.”
- “Losing the final after playing so well stinks.”
This means the situation is disappointing.
- “The deal stank from the beginning.”
Here, stank is being used figuratively.
- “The whole situation has stunk of bad management.”
This uses stunk figuratively in a perfect construction.
Common Mistakes With Stink, Stank, and Stunk
Mistake 1: Using “stinked” as the normal past tense
Wrong:
“The trash stinked yesterday.”
Better:
“The trash stank yesterday.”
Also heard in everyday English:
“The trash stunk yesterday.”
For formal writing, stank is the clearer traditional simple-past choice.
Mistake 2: Using “stank” after “has”
Wrong:
“The room has stank all day.”
Correct:
“The room has stunk all day.”
After has, use the past participle stunk.
Mistake 3: Using “stank” after “had”
Wrong:
“The basement had stank for weeks.”
Correct:
“The basement had stunk for weeks.”
Again, had + past participle requires stunk.
Mistake 4: Using “stunk” when simple past is being taught
If you are learning the traditional irregular-verb pattern, you may be expected to write:
“The garbage stank yesterday.”
rather than:
“The garbage stunk yesterday.”
The second form is common in real-world speech, but stank is the conventional simple-past form taught in many grammar references.
Mistake 5: Confusing “stink” with “stinking”
Incorrect:
“The garbage is stink.”
Correct:
“The garbage is stinking.”
Or:
“The garbage stinks.”
Use stinking after is/are/was/were in a progressive construction.
Mistake 6: Treating every use of “stink” as literal
“That idea stinks.”
This does not necessarily mean the idea has a smell.
It is a figurative expression meaning the idea is bad or unpleasant.
Stink vs Stank vs Stunk in American and British English
There is no simple rule such as “one is American and one is British.”
Stink, stank, and stunk are all found across major varieties of English.
The interesting difference is often usage preference, especially between stank and stunk in the simple past.
American English commonly uses stunk as a simple past form in informal speech:
“That place stunk.”
British English also has both stank and stunk in established usage, although individual speakers and contexts may favor one form.
For international English, the safest strategy is not to label one as “American” and the other as “British.”
Instead, remember their grammatical pattern:
- stink — base/present
- stank — traditional simple past
- stunk — past participle
- stunk — also used as simple past by many speakers
Formal vs Informal Usage
The word stink itself is perfectly legitimate English, but it can sound informal or blunt when describing odors.
Compare:
Casual:
“The bathroom stinks.”
Neutral:
“The bathroom smells bad.”
More formal:
“The bathroom has an unpleasant odor.”
The right choice depends on your audience.
Everyday conversation
Stink is completely natural:
“Something stinks.”
Professional writing
You may prefer:
“There is an unpleasant odor in the storage area.”
Academic writing
A technical description is usually better:
“The sample produced a strong unpleasant odor.”
This is not because stink is grammatically wrong. It is because professional and academic writing often favors more precise or neutral vocabulary.
Pronunciation: Stink, Stank, and Stunk
These three words have different vowel sounds.
| Word | Approximate pronunciation |
|---|---|
| stink | “stink” |
| stank | “stank” |
| stunk | “stunk” |
Their spellings are different because the vowel changes as the irregular verb changes form.
Compare the pattern:
stink → stank → stunk
This is similar to:
sing → sang → sung
and:
drink → drank → drunk
Learning the vowel pattern can help you remember the forms rather than memorizing each word separately.
Where Did “Stink” Come From?
Stink is an old Germanic English verb. Its history goes back to Old English and related Germanic forms associated with unpleasant smells.
The modern irregular pattern reflects a very old type of English verb formation in which the vowel changed to indicate tense or grammatical form.
This is called ablaut, a vowel change found in many old Germanic verbs.
You can still see remnants of this pattern in familiar verbs:
- sing → sang → sung
- ring → rang → rung
- drink → drank → drunk
- begin → began → begun
- stink → stank → stunk
That is why adding -ed does not produce the standard forms.
English did not invent stank and stunk as random exceptions. They are survivors of an older verb pattern.
Memory Tricks for Stink, Stank, and Stunk
Memory trick 1: Think “sing”
Use the similar pattern:
sing → sang → sung
Then:
stink → stank → stunk
The middle form has a; the final form has u.
Memory trick 2: “Have” loves “stunk”
When you see:
has / have / had
think:
has stunk
have stunk
had stunk
This is an easy way to remember the past participle.
Memory trick 3: Yesterday → stank
For a simple past sentence:
Yesterday, the room stank.
That gives you a quick default.
Memory trick 4: Today → stink
Today, the room stinks.
Current situation = stink/stinks.
One-line memory rule
Now = stink, simple past = stank, have/has/had = stunk.
Remember that stunk can also appear as a simple past form in common modern usage.

Do “Stank” and “Stunk” Mean Different Things?
