Case Study Section 📚
Workplace Email Example
Incorrect Version ❌
“The monthly report is completed.”
This sentence is not technically wrong, but it sounds stiff and unnatural in everyday business English.
Better Version ✅
“The monthly report is complete.”
This sounds smoother and more professional.
Conversation Example
Natural Dialogue:
Manager: “Is the presentation ready?”
Employee: “Yes, it’s complete.” ✔️
Less Natural:
Employee: “Yes, it’s completed.” ⚠️
Native speakers rarely say this unless emphasizing the action itself.
School Assignment Example
Correct:
- “I completed my homework.”
- “My homework is complete.”
Both are correct because they serve different purposes.
Grammar Rules Explanation 📖
According to standard English grammar references like Merriam-Webster, the word complete primarily functions as both:
- An adjective
- A verb
Meanwhile, completed is specifically the past tense and past participle form of the verb.
Key Grammar Rule
Use “Complete”:
- After linking verbs like:
- is
- are
- was
- were
- seems
- becomes
Examples:
- “The file is complete.”
- “The puzzle was complete.”
Use “Completed”:
- For past actions
- In passive voice
- As a participial adjective
Examples:
- “She completed the assignment.”
- “The bridge was completed last year.”
Why “The Project Is Completed” Sounds Different
This structure uses the passive voice.
Structure:
- Subject + be verb + past participle
Example:
- “The project is completed.”
This emphasizes the process of completion rather than the current state.
In modern English, people usually simplify it to:
- “The project is complete.”
