The past tense of “fall” is “fell,” and the past participle is “fallen.” Say “the price fell yesterday,” but “the price has fallen since March.” One stands on its own; the other needs has, have, or had in front of it.
The word “falling” is not a tense at all, which is where this question usually starts. It is the -ing form, and it only becomes past when you pair it with was or were: “the rain was falling all night.”
Fell or Fallen: The Helper Test
Both are past forms, and one question separates them: is there a helping verb in the sentence?
- No helper, use “fell”: “He fell off the ladder.” “Temperatures fell overnight.”
- Helper present, use “fallen”: “He has fallen off the ladder twice.” “Temperatures had fallen before dawn.” “A tree was fallen across the road.”
Look for has, have, had, was, or were. If one of them appears, the sentence wants “fallen.” If none does, “fell” is the form you need, and no exceptions apply.
The most common error in English writing on this verb is “I have fell,” which mixes the two: the helper have demands the participle, so it must be “I have fallen.” The reverse error, “he fallen down,” is rarer but equally wrong, since a participle cannot stand alone as the main verb.
Why “Falling” Sends People Looking
“Falling” is the present participle, and it describes an action in progress rather than a point in time. It cannot be past or present by itself; the helping verb carries the tense.
- Present continuous: “The snow is falling.”
- Past continuous: “The snow was falling.”
- Future continuous: “The snow will be falling by then.”
So the past of “falling” is really “was falling” if you want the action stretched over time, and “fell” if you want it as a completed event. “The snow was falling when we left” and “the snow fell overnight” both describe the past, but only the second one closes the action.
Every Form of “Fall” in One Table
| Form | Word | Example |
|---|---|---|
| Base / present | fall | Leaves fall in October. |
| Third person singular | falls | The temperature falls at night. |
| Simple past | fell | The vase fell off the shelf. |
| Past participle | fallen | The vase has fallen twice. |
| Present participle | falling | The vase is falling. |
| Future | will fall | Prices will fall next quarter. |
“Fall” is an irregular verb, so none of these are built by adding -ed. Writing “falled” is never correct, in any variety of English. Merriam-Webster’s entry for “fall” lists the inflected forms as fell, fallen, falling, with no -ed variant anywhere in the paradigm. The same pattern governs the other irregular verbs whose participles end in -en, including choose, chose, and chosen.
Phrasal Verbs: Fall Down, Fall Off, Fall in Love
Every phrasal verb built on “fall” keeps the same past forms, because the particle after it never changes the verb itself. This trips people up because the phrase feels like a new word.
| Phrasal verb | Past | Past participle | Example |
|---|---|---|---|
| fall down | fell down | fallen down | She fell down the last two steps. |
| fall off | fell off | fallen off | The handle fell off in my hand. |
| fall apart | fell apart | fallen apart | The plan fell apart by Tuesday. |
| fall through | fell through | fallen through | The sale fell through last week. |
| fall behind | fell behind | fallen behind | He fell behind on the reading. |
| fall in love | fell in love | fallen in love | They fell in love in Lisbon. |
| fall asleep | fell asleep | fallen asleep | I fell asleep before the credits. |
Note “fell in love,” not “falled in love” or “fell in loved.” The irregular past sits on the verb, and the rest of the phrase stays exactly as it is.
“Fallen” Also Works as an Adjective
Outside the verb system, “fallen” describes something already on the ground or already brought down: “a fallen branch,” “fallen leaves,” “a fallen empire.” No helping verb is needed here because the word is no longer acting as a verb at all.
“Fell” never does this job. “A fell branch” is not English in this sense, and the mistake is easy to spot once you know the split: in front of a noun, the form is always “fallen.”
One curiosity worth knowing is that “fell” exists as a separate adjective meaning fierce or deadly, surviving mainly in the phrase “one fell swoop.” That word has nothing to do with the verb “fall,” which is why it looks like an exception and is not one.
“Had Fallen” vs “Fell”: Which Past Comes First
Both describe the past, and “had fallen” places an event further back than another past event in the same sentence.
- “By the time we arrived, the tree had fallen.” (The falling happened before the arriving.)
- “We arrived, and the tree fell.” (Two events in sequence.)
Use “had fallen” only when you need that earlier-than-the-past layer. If a single past moment is all you are describing, “fell” is correct and adding the helper makes the sentence heavier without adding meaning.
Four Errors Worth Checking For
| Wrong | Right | Why |
|---|---|---|
| I have fell behind. | I have fallen behind. | A helping verb requires the participle. |
| The vase falled off. | The vase fell off. | “Fall” is irregular; no -ed form exists. |
| He fallen asleep early. | He fell asleep early. | A participle cannot be the main verb alone. |
| Yesterday I fall down. | Yesterday I fell down. | A past time marker forces the past tense. |
“I Fell” or “I Fall”?
Both are correct English, and they describe different times. “I fall” is present tense, used for habits and general truths: “I fall asleep on every long flight.” “I fell” is simple past, used for one completed event: “I fell asleep during the second act.”
If the sentence has a past time marker in it, such as yesterday, last night, or in 2019, the verb must be “fell.” Present tense with a past marker is one of the clearest errors in English, which makes the time marker a reliable check when you are unsure.
Two Checks That Settle It
First, scan for a helping verb. Has, have, or had means “fallen”; nothing means “fell.” Second, scan for a time marker. A specific past time means simple past, and an ongoing stretch of past time means “was falling.” Between them, those two checks resolve every sentence this verb appears in, the same way the swap tests do for tricky punctuation like commas with “but.”
FAQ: Past Tense of “Fall”
How do you say “fall” in the past?
Use “fell” for a completed action: “the branch fell.” Use “had fallen” or “has fallen” when a helping verb is present, and “was falling” when the action was ongoing at the time you are describing.
Is it “fallen” or “fell”?
“Fell” is the simple past and stands alone. “Fallen” is the past participle and needs has, have, had, was, or were with it. “I have fell” is always incorrect; write “I have fallen.”
What is the past tense of “fall off”?
“Fell off.” Every phrasal verb built on “fall” keeps the irregular past: fell down, fell apart, fell through, fell behind, fell in love. The particle never changes the verb form.
Which is correct, “I fell” or “I fall”?
Both, in different tenses. “I fall” describes a habit or general truth; “I fell” describes one completed past event. A past time marker such as “yesterday” always requires “fell.”
One line to keep: fell needs nothing, fallen needs a helper, and falling needs a form of “be” before it can point anywhere in time at all.
