Quick Answer
The past tense of fall down is fell down, while the past participle of fall down is fallen down. Because fall is an irregular verb, only the verb changes tense, and down stays the same. For example, “She fell down yesterday” is correct, while “She has fallen down twice this week” uses the past participle correctly.
What Does “Fall Down” Mean?
The phrase fall down means to lose your balance and move from a higher position to the ground. It is commonly used when a person, animal, or object accidentally drops because it cannot stay upright.
In everyday English, people often use fall down to describe accidents, slips, or trips. The word fall is the main verb, while down adds emphasis by showing the direction of the movement. For example, you can say, “The child fell down while running in the park.”
Although fall and fall down have similar meanings, fall down usually sounds more specific because it highlights the movement toward the ground. Understanding this meaning makes it easier to learn the past tense of fall down and use it correctly.
What Is the Past Tense of “Fall Down”?
The past tense of fall down is fell down. Since fall is an irregular verb, it does not become falled. Instead, it changes to fell, while the word down remains the same. This means you should always say fell down when talking about something that happened in the past.
For example, “She fell down the stairs yesterday,” and “The bicycle fell down during the race” are both correct. Many English learners mistakenly write fall downed or falled down, but these forms are incorrect.
If you remember the verb pattern fall → fell → fallen, choosing the correct fall down past tense becomes much easier in both speaking and writing.
Past Participle of “Fall Down”
The past participle of fall down is fallen down. This form is used with helping verbs such as has, have, and had to make perfect tenses.
For example, “He has fallen down twice this week” and “The old tree had fallen down before the storm ended” are correct sentences. A common mistake is saying has fell down, but this is not correct because fell is only the simple past tense.
The correct verb pattern is fall – fell – fallen. Learning the difference between fell down and fallen down helps you write accurate English and avoid common grammar errors that many learners make.

Why “Fall Down” Is Not a Separate Verb
Many learners think fall down is a completely different verb, but it is actually a verb phrase. The word fall is the only verb, while down is an adverb that describes the direction of the action. When changing tenses, only the verb changes, and down always stays the same.
That is why fall down becomes fell down in the simple past and fallen down in the past participle. Understanding this rule helps you avoid many grammar mistakes.

How to Use “Fell Down” Correctly
Use fell down whenever you describe an action that happened and finished in the past. It works in positive sentences, negative sentences, and questions.
For example, “I fell down while playing football,” “She did not fall down during the performance,” and “Did they fall down on the icy road?” are all correct. Notice that after did or did not, the verb returns to its base form fall, not fell.
This is an important grammar rule that many learners forget. By practicing these sentence patterns, you will use the past tense of fall down naturally and speak or write English with greater confidence.
How to Use “Fallen Down” Correctly
The phrase fallen down is the past participle of fall down and is always used with helping verbs such as has, have, or had. You cannot use fallen down by itself as the main verb in a simple past sentence.
For example, “She has fallen down three times this month” and “The old fence had fallen down before the workers arrived” are correct. However, “She fallen down yesterday” is incorrect because it needs a helping verb.
Remember the verb pattern fall – fell – fallen whenever you write or speak. Learning when to use fallen down will improve your grammar and help you avoid one of the most common mistakes made by English learners.
Common Mistakes Learners Make
Many learners confuse fell down and fallen down, but understanding a few simple rules makes the difference clear. The most common mistake is writing “I have fell down,” which is incorrect. The correct sentence is “I have fallen down.”
Another error is “She fallen down yesterday.” Since yesterday shows the simple past tense, the correct form is “She fell down yesterday.” Some learners also write falled down, but fall is an irregular verb, so this form is never correct.
Always remember the pattern fall – fell – fallen. Checking your sentence for time words and helping verbs will help you choose the correct verb form every time.
Fall vs. Fall Down vs. Fall Over
Although fall, fall down, and fall over are closely related, they are not always used in the same way. In general, fall means to drop from a higher position or lose balance. In everyday conversations, fall down usually emphasizes moving all the way to the ground.
By contrast, fall over often describes tipping from an upright position onto one side. For example, you might say, “The apple fell from the tree,” “The child fell down while running,” or “The chair fell over because someone pushed it.”
Knowing these small differences helps you choose the most natural expression and improves both your spoken and written English.

“The old bookshelf fell down during the earthquake.” “Be careful, or you might fall down the stairs.” “The workers said the wall had fallen down before they arrived.” These examples show how fall down, fell down, and fallen down are used in different situations.
