The antonym for assert is deny. When you assert something, you state it confidently and forcefully. On the other hand, to deny means to declare that something is not true or to refuse to accept or acknowledge something.
For example:
- Assert: “She asserted that she had completed the project on time.”
- Deny: “He denied any involvement in the incident.”
Understanding the difference between these two words can help in clearly expressing agreement or disagreement in various contexts.
