Is about a fragment sentence?

A fragment sentence is an incomplete sentence that lacks the necessary elements to stand on its own as a grammatically complete thought. It is missing key components such as a subject, a verb, or both, and as a result, it cannot convey a complete idea.

Examples of fragment sentences include:

- Swimming in the ocean.

- My favorite color.

- When it rains.

These sentences are grammatically incomplete because they lack essential information. To create complete sentences, they would need to be expanded by adding the missing elements:

- I love swimming in the ocean.

- My favorite color is blue.

- I enjoy running when it rains.

By providing the necessary information, these sentences become grammatically complete and convey clear and complete thoughts.
