Past Form Of Show | Verb Forms And Examples

English learners often pause when they reach the past form of the verb show. You’ll hear both showed and shown, and that can feel confusing at first glance.

The short answer is this: showed is the simple past form, and shown is the past participle form that works with helper verbs like have, has, and had. Both appear in everyday speech and writing.

This guide walks you through each main pattern, gives clear examples, and points out frequent errors so you can choose the right form with confidence in your own sentences.

Past Form Of Show In English Grammar

When learners search for the past form of show, they usually want to know two things: the simple past form and the past participle form. In standard modern English, the simple past is showed, and the past participle is shown. Major grammar references list the verb as “show – showed – shown.”¹

The verb counts as irregular because the past participle does not simply reuse the simple past form. Some dictionaries mention that showed can appear as a past participle in certain styles, yet shown is far more common and safer for exams, formal writing, and careful speech.²

Core Forms Of Show At A Glance

Form	Grammar Use	Example Sentence
show	Base form / infinitive	I want to show you this chart.
shows	Present simple (third person)	The diagram shows the main steps.
showed	Simple past	She showed me her homework yesterday.
shown	Past participle	They have shown great skill this term.
showing	Present participle / -ing form	He is showing the class a new method.
was / were showing	Past continuous	The teacher was showing us the answers.
has / have shown	Present perfect	The results have shown clear progress.
had shown	Past perfect	By then, he had shown them every step.

That table gives a quick map of the verb family. Notice how showed stands alone as the simple past form, while shown only appears with helper verbs such as has, have, or had, or inside passive sentences.

Grammar resources like the Cambridge Dictionary entry for “show” and the Cambridge irregular verb table present the same pattern, so you can rely on it in tests and academic writing.³⁴

How The Past Forms Fit Into Tenses

The simple past form showed stands on its own. You don’t add another main verb to it. The past participle shown never stands alone as the main verb; it always comes after a helper verb such as have, has, or had, or after form of be in passive voice.

So, if you only change the time of a sentence and keep the basic meaning, you’ll shift between these forms:

• Present: I show the class my notes.
• Simple past: I showed the class my notes.
• Present perfect: I have shown the class my notes.
• Past perfect: I had shown the class my notes before the test.
• Passive: The notes were shown to the class.

The phrase past form of show in many textbooks covers both showed and shown, because both relate to time before now, but they sit in different slots inside the sentence.

Past Tense Of Show In Real Sentences

The simple past form showed describes an action that finished at a clear time in the past. You usually see it with time words such as yesterday, last week, in 2020, or with a specific event that no longer continues.

Use showed when you tell a story, describe a finished lesson, or report past results. No helper verbs are needed; showed carries the time meaning on its own.

Typical Patterns With Showed

Here are some common patterns where showed fits naturally:

• Subject + showed + object
  She showed me the correct answer.
• Subject + showed + object + object
  The coach showed the team a new drill.
• Subject + adverb + showed + object
  He patiently showed them each step.
• Subject + showed + that-clause
  The graph showed that scores had risen.
• Subject + showed + noun phrase
  The results showed clear progress.

These patterns work in both spoken and written English. The verb showed often carries two objects: one person and one thing, as in “She showed the class the slide.” Both orders are possible, as long as the meaning stays clear: “She showed the slide to the class” also works.

Time Expressions With Showed

Simple past sentences with showed frequently contain a time expression that sets the scene. Some popular choices include:

• Yesterday, the teacher showed us a new trick.
• Last week, my friend showed me a useful app.
• Two days ago, the guide showed them the museum.
• In 2019, the data showed a different pattern.
• At the end of the lesson, she showed a short video.

The time phrase can move to the end of the sentence as well: “The teacher showed us a new trick yesterday.” The verb stays as showed in each case.

Using Shown As The Past Participle

The form shown appears as a past participle. That means it comes after helper verbs or after a form of be. It does not appear alone in a simple past statement. Grammar tables for irregular verbs group shown with other past participle forms that end in “-n,” such as known or taken.⁵

You’ll see shown in perfect tenses and passive voice. These structures help connect past events to another time or shift focus from the person doing the action to the thing that receives it.

Present Perfect With Shown

Use has shown or have shown when a past action connects to the present. Maybe the time is not clear, or the result still matters now.

• She has shown me this trick many times.
• They have shown strong effort during the course.
• The chart has shown the same pattern all year.

Notice that shown always follows has or have in these sentences. Writing “has showed” is common in learner writing, yet style guides and dictionaries prefer “has shown.”²

Past Perfect With Shown

The past perfect form had shown marks an action that finished before another point in the past. It often appears in storytelling, reports, and exam answers.

• By the time the test started, the teacher had shown us every sample question.
• The experiment had shown clear results before funding ended.
• We moved on only after the video had shown the full process.

Here, the reference point also sits in the past. The past perfect pair “had shown” looks back to an earlier completed action.

Passive Voice With Shown

In passive sentences, shown appears after a form of be. The object of the active sentence becomes the subject of the passive sentence.

• Active: The tutor showed the method to the group.
  Passive: The method was shown to the group.
• Active: The presenter has shown the slides already.
  Passive: The slides have been shown already.
• Active: The coach will show the drill on Monday.
  Passive: The drill will be shown on Monday.

Passive voice lets you stress the thing or result. In each passive example, shown stays in its participle form, while the helper verb changes for time and subject.

Common Mistakes And Easy Fixes

Many learners mix up showed and shown. Some use showed wherever a past idea appears. Others put shown after did or on its own in simple past sentences. A second mention of the phrase past form of show often appears when students correct those patterns in class notes.

The table below matches typical errors with better options. It can work as a quick check while you write or edit your own work.

Typical Errors With Showed And Shown

Situation	Common Error	Correct Form
Simple past statement	He has showed me the way yesterday.	He showed me the way yesterday.
Present perfect	She has showed us the report.	She has shown us the report.
Past perfect	They had showed the results before lunch.	They had shown the results before lunch.
Passive past simple	The film was showed in class.	The film was shown in class.
Passive perfect	The slides have been showed already.	The slides have been shown already.
Question in simple past	Did you showed your work?	Did you show your work?
Negative simple past	He didn’t showed the steps.	He didn’t show the steps.

In the last two rows, the helper verb did already carries the past meaning, so the main verb returns to the base form show. This pattern matches all regular and irregular verbs in English questions and negatives in simple past.

The other rows show that shown combines with helper verbs, while showed stands alone as the main verb in simple past. Once you spot the helper, the choice between showed and shown becomes much easier.

Quick Review Of Show In The Past

To close, here is a short review you can keep in mind while writing or speaking. Use showed when you need a simple past verb with no helper. Use shown when you build a perfect tense or passive sentence with helper verbs such as have, has, had, or forms of be.

• Simple past: They showed us the project last week.
• Present perfect: They have shown us the project already.
• Past perfect: They had shown us the project before the review.
• Passive: The project was shown during the meeting.

With regular practice, the structure will start to feel natural. Reading short grammar tables, checking trusted references, and noticing how teachers and writers use showed and shown in real contexts will steadily build your control of this useful verb.
