When it comes to using the words “complete” and “completed,” it can be confusing to know which one to use in different situations.
The key difference between the two is that “complete” is an adjective, while “completed” is the past participle form of the verb “complete.”
The good news is that they are generally interchangeable in common usage across the board in English. Both “complete” and “completed” are correct, and they are about as popular as each other, though “complete” is slightly more popular.
Here are some examples to help you understand the difference:
- “The puzzle is complete.” (adjective)
- “I have completed the puzzle.” (verb)
In the first example, “complete” is used as an adjective to describe the state of the puzzle. In the second example, “completed” is used as the past participle form of the verb “complete” to indicate that the puzzle has been finished.
Take note that “complete” can also be used as a verb, but it’s less common than using “completed” as the past participle form of the verb “complete.” When using “complete” as a verb, it means to make something whole or to finish something.
Here are some more examples to help you understand how to use “complete” and “completed” correctly:
- “The project is complete.” (adjective)
- “I have completed the project.” (verb)
- “The form is complete.” (adjective)
- “I have completed the form.” (verb)
Grammatical Context
When deciding whether to use “complete” or “completed,” the first thing to consider is the grammatical context of the sentence. For example, “complete” is often used as an adjective to describe something that is whole or contains all the necessary parts. On the other hand, “completed” is the past tense of the verb “complete” and is used to describe an action that has already been finished.
When using “complete” as an adjective, make sure that it agrees with the noun it is modifying. For example, you would say “the project is complete,” but “the completed project was submitted on time.” In the first sentence, “complete” is used as an adjective to describe the state of the project, while in the second sentence, “completed” is used as the past participle of the verb “complete” to describe the action of submitting the project.
When using “completed” as a verb, consider the tense of the sentence. For example, you would say “I completed the project yesterday,” using the past tense of the verb “complete.” If you wanted to use the passive voice, you could say “the project was completed yesterday,” using the past participle of the verb “complete.”
Consider the context of the sentence when deciding whether to use “complete” or “completed.” For example, if you are talking about a job assignment, you might say “the complete job assignment includes a full set of instructions and a due date,” using “complete” as an adjective to describe the job assignment. However, if you are talking about a completed job assignment, you might say “the completed job assignment resulted in payment for services rendered,” using “completed” as the past participle of the verb “complete” to describe the action of finishing the job assignment.

Common Mistakes and Misunderstandings
There are a few common mistakes and misunderstandings when it comes to using “complete” or “completed.” Here are some of the key things to keep in mind:
- Using “complete” and “completed” interchangeably: While “complete” and “completed” can both be used to describe something that has finished, they are not always interchangeable. “Complete” is an adjective that describes something that is finished, while “completed” is the past tense of the verb “complete.” So, for example, you might say “The project is complete” to describe a finished project, or “I have completed the project” to describe the act of finishing it.
- Misunderstanding the difference between “is complete” and “has been completed”: Another common mistake is to use “is complete” and “has been completed” interchangeably. While both phrases describe something that is finished, they have slightly different meanings. “Is complete” is a statement about the current state of something, while “has been completed” is a statement about the past action of completing something. So, for example, you might say “The project is complete” to describe the current state of a finished project, or “The project has been completed” to describe the past action of finishing it.
- Messing up verb tenses: When using “complete” and “completed” in sentences, it’s important to pay attention to verb tenses. For example, if you’re describing a project that you finished yesterday, you might say “I completed the project yesterday” (using the past tense) rather than “I complete the project yesterday” (using the present tense).
By keeping these common mistakes and misunderstandings in mind, you can use “complete” and “completed” correctly and effectively in your writing and speaking.
