3. Common Mistakes with the Future Perfect Tense
Even though the future perfect is simple to understand, learners often make a few mistakes when using it. Let’s go over how to avoid these pitfalls!
Mistake #1: Using the Future Perfect When It’s Not Necessary
Sometimes, learners use the future perfect when the simple future tense would do just fine. Only use the future perfect when you’re focusing on something that will be completed by a certain time.
- Incorrect: I will have finish my homework tomorrow.
(This mixes tenses and doesn’t need the future perfect.) - Correct: I will finish my homework tomorrow.
(Just a simple future statement.) - Correct: By tomorrow, I will have finished my homework.
(This shows that the homework will be done by tomorrow.)
Tip: If you’re just talking about a future action with no reference to completion, stick with the simple future tense.
Mistake #2: Forgetting the “Have” in the Future Perfect
The future perfect needs the word “have” to be complete. Forgetting it is a common mistake.
- Incorrect: I will finished the report by 5 PM.
- Correct: I will have finished the report by 5 PM.
Tip: Don’t forget to include “have” between “will” and the past participle.
Mistake #3: Mixing the Future Perfect with Other Tenses
The future perfect is specific to actions that will be completed before a certain point in the future, so it shouldn’t be mixed up with the present or past tenses.
- Incorrect: By next month, I have finished my course.
- Correct: By next month, I will have finished my course.
Tip: Stick to “will have” + past participle when using the future perfect to talk about future completions.
