Common Mistakes When Using Lost or Found
Although the meanings are straightforward, writers sometimes confuse these words or use the wrong verb form.
Mistake 1: Using Found When Something Is Still Missing
Incorrect: I found my keys, but I still cannot locate them.
Correct: I lost my keys, but I still cannot locate them.
Use lost when the keys are missing. Use found after you have located them.
Mistake 2: Using Lost Instead of Found
Incorrect: I lost my wallet under the desk and picked it up.
Better: I found my wallet under the desk and picked it up.
The second sentence clearly describes discovering the wallet. The first would suggest that the wallet went missing, so the intended meaning is less clear.
Mistake 3: Writing Finded Instead of Found
Incorrect: She finded her missing notebook.
Correct: She found her missing notebook.
Find is an irregular verb, so its simple past form is found, not finded.
Mistake 4: Confusing Found With Founded
Incorrect: They found a school in 1995, meaning they established it.
Correct: They founded a school in 1995.
Use founded when talking about establishing a school, business, institution, or organization. Use found when talking about discovering or locating something.
Mistake 5: Mixing Up Lost and Lose
Incorrect: I loose my keys every week.
Correct: I lose my keys every week.
Lose is the present tense verb. Lost is its past tense and past participle. Loose is a different word that usually means not tight.
