If you’re confused about shown vs showed, the key is simple: showed is normally the simple past tense of show, while shown is normally the past participle. For example, “She showed me the report yesterday” uses the simple past, while “She has shown me the report” uses the past participle. Cambridge Dictionary lists showed as the past tense and shown as the past participle. Merriam Webster likewise gives showed and shown as the main forms of show.
The important clue is the word before the verb. If you have a helping verb such as has, have, had, is, was, or were, the correct form often depends on the grammatical structure. Learning this pattern makes the difference between showed and shown much easier to remember.
Definition
Showed and shown are two forms of the irregular verb show.
The basic forms are:
| Verb form | Word | Example |
|---|---|---|
| Base form | show | I show the results. |
| Simple past | showed | I showed the results. |
| Past participle | shown | I have shown the results. |
| Present participle | showing | I am showing the results. |
The main distinction is grammatical:
Showed = simple past
Shown = past participle
For most standard English writing, this is the rule to follow.
Understanding the Verb “Show”
The verb show has several related meanings. It can mean to make something visible, explain something, demonstrate something, reveal information, or guide someone.
Examples include:
- “Please show me your notes.”
- “The chart shows a steady increase.”
- “She showed me how to use the software.”
- “The results have shown a clear pattern.”
- “He showed great patience during the meeting.”
Because show is an irregular verb, its past forms don’t follow the regular pattern used by verbs such as walk or worked.
You don’t say:
“Yesterday, I show the report.”
You say:
“Yesterday, I showed the report.”
And when a perfect tense requires a past participle, you normally say:
“I have shown the report.”
When to Use “Showed” The Simple Past Tense
Use showed when you are describing an action that happened in the past.
The simple past usually presents the event as completed.
Examples
Here are some natural examples:
- “I showed my teacher the assignment yesterday.”
- “She showed us her new apartment.”
- “They showed the customer several options.”
- “He showed me the correct answer.”
- “The presentation showed how the system works.”
- “The report showed a significant change.”
- “We showed the visitors around the office.”
Notice that these sentences don’t need have, has, or had before showed.
When to Use It
Use showed when:
- The action happened at a specific past time.
- You are describing a completed past event.
- The sentence uses a simple past structure.
- You don’t need a past participle after a perfect auxiliary.
Common time expressions include:
- yesterday
- last week
- last year
- two hours ago
- in 2024
- earlier this morning
- when I was younger
For example:
“Maria showed me the document yesterday.”
The word yesterday strongly supports the simple past.
When to Use “Shown” The Past Participle
Shown is normally the past participle of show. It is used with auxiliary verbs in perfect tenses and in passive constructions.
For example:
“I have shown him the results.”
“She had shown us the evidence.”
“The results were shown to the team.”
Cambridge Dictionary identifies shown as the past participle of show.
Examples
Here are common examples using shown:
- “I have shown you the correct file.”
- “She has shown remarkable improvement.”
- “They had shown us the original design.”
- “The data has shown a clear trend.”
- “The results have shown that the method works.”
- “The documents were shown to the manager.”
- “He was shown the way to the conference room.”
The important point is that shown usually needs a grammatical structure that supports a past participle.
How to Spot It
Look for a helping verb.
Common combinations include:
- have shown
- has shown
- had shown
- have been shown
- has been shown
- had been shown
- was shown
- were shown
If you see have, has, or had, shown is usually the form you want.
For example:
“Researchers have shown that regular practice improves performance.”
Not:
“Researchers have showed that regular practice improves performance.”
Why “Shown” Matters in Perfect Tenses
Perfect tenses connect a past action with another point in time.
The three major perfect structures are:
Present perfect: have or has + past participle
Past perfect: had + past participle
Future perfect: will have + past participle
Since shown is the standard past participle of show, it fits these structures.
Examples:
“Scientists have shown the relationship.”
“The study had shown a different result.”
“By next year, the project will have shown whether the approach works.”
This is why have shown sounds natural to most modern English speakers, while have showed is generally avoided in standard writing.
Merriam Webster lists shown as the past participle while also noting that showed can occur as an alternative in some usage.
Breaking Down Perfect Tenses With “Shown”
Present Perfect
Have or has + shown
Examples:
“I have shown you the results.”
“She has shown excellent leadership.”
“The evidence has shown a consistent pattern.”
Present perfect is useful when the past action has relevance to the present or when the exact past time isn’t the main focus.
Past Perfect
Had + shown
Examples:
“She had shown me the document before the meeting.”
“The earlier test had shown different results.”
Past perfect places one past event before another past event.
Future Perfect
Will have + shown
Examples:
“By Friday, the research team will have shown whether the model works.”
“By the end of the project, the results will have shown its overall impact.”
“Have Showed” vs “Have Shown” The Grammar Test
For standard modern English, choose:
Have shown
Example:
“Studies have shown that practice improves accuracy.”
Avoid using:
“Studies have showed that practice improves accuracy.”
The reason is grammatical rather than stylistic. Have is an auxiliary used to form the present perfect, so it is followed by a past participle. The standard past participle of show is shown. Cambridge explicitly identifies shown as the past participle.
Pronunciation Flow
In natural speech, showed and shown have different endings.
- showed ends with a /d/ sound
- shown ends with an /n/ sound
That difference can make the forms easier to distinguish when listening.
You can also remember the pattern:
Yesterday: showed
Have or has: shown
For example:
“I showed it yesterday.”
“I have shown it before.”
Real Life Examples and Common Usage Notes
Consider these everyday examples:
Simple past:
“James showed me his new phone yesterday.”
Present perfect:
“James has shown me his new phone several times.”
Past perfect:
“James had shown me the phone before I bought one.”
The meaning is closely related, but the tense changes the relationship between the action and the time reference.
Regional Note
There is some variation in how showed and shown have been used historically and regionally.
Modern standard English strongly favors shown as the past participle, especially in formal writing and international English. Some dictionaries and language references acknowledge showed as an alternative past participle in certain varieties or older usage. Merriam Webster lists “shown or showed” in its verb forms, while Cambridge gives shown as the past participle.
For learners, the safest practical rule is:
Use showed for the simple past and shown for the past participle.
That choice will sound natural and standard in most contexts.

Quick Memory Tips to Remember
Use these simple memory rules.
Tip 1: Yesterday Means Showed
If the sentence describes a completed past action with a clear past time, showed is usually correct.
“Tom showed me the photo yesterday.”
Tip 2: Have, Has, or Had Means Shown
After have, has, or had, use shown in standard English.
“I have shown you.”
“She has shown us.”
“They had shown the results.”
Tip 3: Remember the Three Forms
Show → showed → shown
Think:
Today → show
Yesterday → showed
Have or had → shown
Tip 4: Watch for Passive Voice
Passive sentences commonly use shown:
“The results were shown to the committee.”
“The evidence was shown during the presentation.”
Common Mistakes and How to Avoid Them
Mistake 1: Using “Showed” After Have
Incorrect:
“I have showed him the document.”
Better:
“I have shown him the document.”
Mistake 2: Using “Shown” as the Simple Past
Incorrect:
“Yesterday, she shown me the results.”
Correct:
“Yesterday, she showed me the results.”
Mistake 3: Thinking Both Forms Are Interchangeable
They are related, but they normally perform different grammatical roles.
Compare:
“She showed me the answer.”
“She has shown me the answer.”
The first uses simple past. The second uses present perfect.
Mistake 4: Forgetting Passive Voice
Correct:
“The presentation was shown to the audience.”
Not:
“The presentation was showed to the audience.”
Case Study: A Common Workplace Mix Up
Imagine an employee writing an email about a project report.
They write:
“Hi, the latest figures have showed a significant improvement.”
The sentence sounds understandable, but the standard form is:
“Hi, the latest figures have shown a significant improvement.”
Why?
The word have signals the present perfect. The verb that follows must be in its past participle form. For show, that standard form is shown.
Now consider a different sentence:
“The latest figures showed a significant improvement last month.”
Here, showed is correct because the sentence uses the simple past and specifies a completed past period.
This small distinction matters in workplace emails, reports, academic writing, presentations, and professional communication.
Linguistic Insight and Expert Opinion
The confusion exists because show has more than one past form in modern English.
Many regular verbs use the same form for their simple past and past participle. For example:
“worked” can function as both.
But show traditionally distinguishes the forms:
showed = simple past
shown = past participle
This makes show similar to other irregular verbs such as:
- write, wrote, written
- take, took, taken
- see, saw, seen
- speak, spoke, spoken
The modern learner friendly pattern is therefore straightforward:
show, showed, shown
Dictionary evidence supports this distinction. Cambridge identifies showed as the past tense and shown as the past participle, while Merriam Webster records shown as the primary participle and acknowledges showed as an alternative in some usage.
Historical and usage discussions also show that showed has occasionally appeared as a past participle. However, that usage is much less useful as a model for learners than the standard shown pattern.

Answers

The pattern is consistent: simple past uses showed, while perfect and passive structures normally use shown.
Final Conclusion
The difference between shown and showed becomes easy once you identify the verb form required by the sentence.
Use showed as the simple past:
“She showed me the picture yesterday.”
Use shown as the standard past participle:
“She has shown me the picture.”
The most useful rule is:
Showed = simple past.
Shown = past participle.
When you see have, has, or had, think shown. When you’re describing a completed action at a specific past time, think showed.
Although showed can appear as an alternative past participle in some varieties and older usage, shown is the safest and most widely accepted choice for standard modern English, especially in formal, academic, and professional writing.
