Here's why it might be used:
* To describe verbs that create a strong visual image: For example, "The lion roared" is more vivid than "The lion made a noise."
* To emphasize the action: "The artist painted a beautiful sunset," highlighting the physical act of painting.
* In contrast to abstract verbs: "He felt sad" is less visible than "He cried."
Possible interpretations:
* In creative writing: "Visible verbs" could refer to verbs that contribute to a stronger sense of imagery and sensory experience.
* In technical writing: "Visible verbs" could refer to verbs that clearly describe the action performed, like "The machine operated successfully" instead of "The machine functioned."
Ultimately, the meaning of "visible verb" depends on the context in which it's used.
If you can provide more context, I might be able to give you a more precise explanation.
