Find out vs. Found out – Which is Correct?
Find out is the present/base form of the phrasal verb meaning to discover or learn something. Found out is its simple past and past participle form. Use find out for facts you discover now or regularly, and found out for discoveries connected to completed events.
Find out or found out – Which is Correct?
Both “find out” and “found out” are correct. They are different forms of the same irregular phrasal verb. Use find out for the present tense, after helping verbs such as “will” or “did,” and in commands. Use found out for a completed discovery in the past or as a past participle with “have,” “has,” or “had.”
The Best Trick to Remember the Difference
Use the timeline trick: if the discovery is happening now or has not happened yet, choose find out. If the discovery already happened, choose found out. Remember that “found” contains “past” in the sense of something already found. For example, “I will find out tomorrow,” but “I found out yesterday.”
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| find out | Phrasal verb; present or base form | To discover or learn information | I need to find out when the train leaves. |
| found out | Phrasal verb; past and past participle form | Discovered or learned information in the past | She found out the truth last night. |
How to Use find out
Find out is the present-tense and base form of the phrasal verb. It means to discover information, obtain an answer, or become aware of a fact. It can describe something happening now, something that happens regularly, or something expected in the future. It is common in both casual and formal English, although “discover” may sound more formal in some contexts.
Use find out after modal verbs and other auxiliary verbs, including “can,” “will,” “should,” “might,” and “did.” It is also used in commands and infinitive phrases.
Example 1: I will find out whether the museum is open on Monday.
Example 2: Can you find out who sent this package?
Example 3: We often find out about schedule changes through email.
What are the different forms of find out?
Find out is an irregular phrasal verb because the verb “find” changes to “found” in the past rather than taking the regular -ed ending. Its principal forms are:
- Base form: find out — I want to find out the answer.
- Third-person singular present: finds out — He finds out the results today.
- Present participle: finding out — She is finding out more about the program.
- Simple past: found out — They found out the news yesterday.
- Past participle: found out — We have found out what caused the problem.
After “did,” always use the base form: Did you find out? Do not say Did you found out? The auxiliary verb “did” already marks the sentence as past tense.
Etymology of the word find out
The verb find comes from Old English findan, meaning “to come upon” or “discover.” The word out developed from an Old English adverb meaning “outside” or “away from.” Together, find out came to express bringing hidden or unknown information into awareness.
How to Use found out
Found out is the simple past and past participle form of find out. Use it when someone discovered or learned something at a completed time in the past. It can also follow “have,” “has,” or “had” in perfect constructions.
In casual conversation, found out is often followed by a clause beginning with “that,” a question word, or an object such as “the truth” or “the answer.”
Example 1: I found out that the meeting had been canceled.
Example 2: She found out where the missing documents were.
Example 3: By the end of the investigation, the reporters had found out the cause of the error.
What are the different forms of found out?
Found out has two grammatical functions. It is the simple past form when it stands alone, as in He found out the truth yesterday. It is the past participle when it follows a form of have, as in He has found out the truth.
- Simple past: found out — I found out the answer last week.
- Present perfect: have or has found out — They have found out what happened.
- Past perfect: had found out — She had found out before I called.
- Future perfect: will have found out — By tomorrow, we will have found out the result.
Do not use found out after “will,” “can,” “should,” or “did.” Use the base form instead: will find out, can find out, should find out, and did find out.
Etymology of the word found out
Found is the irregular past and past participle of find, a verb inherited from Old English. When combined with out, it retains the meaning of discovering information. The form indicates that the discovery is viewed as completed or connected to a completed time.
Related Concepts
Understanding verb tense, auxiliary verbs, and phrasal verbs makes the difference between find out and found out easier to recognize.
- Irregular verbs: An irregular verb does not form its past tense by simply adding -ed. The verb find changes to found.
- Phrasal verbs: A phrasal verb combines a verb with an adverb or preposition to create a particular meaning. In find out, the word out changes the meaning of find.
- Auxiliary verbs: Helping verbs such as did, will, and have affect which form follows them. Use find after “did” and “will,” but use found after “have” or “had.”
- Verb tense: Present or future contexts generally use find out, while completed past events use found out.
Examples from Media and Literature
The two forms appear frequently in storytelling, journalism, and everyday dialogue. These examples show how the tense changes with the context:
- Detective fiction: A detective may say, “We will find out who entered the building,” when describing an investigation that is still in progress.
- Historical novels: A narrator might write, “The travelers found out that the bridge had collapsed,” describing a completed discovery.
- News reporting: A report may state, “Officials are working to find out what caused the outage,” because the answer is not yet known.
- Film dialogue: A character may say, “I found out the truth from an old letter,” because the discovery occurred earlier.
- Memoirs: An author might write, “Years later, I found out why my family had moved,” using the past form for a later realization.
