What does the prefix "re-" generally indicate when added to a verb?

The prefix "re-" is commonly used in the English language to signify that an action is being repeated or done again. For instance, when the prefix is added to the verb "write," it forms the word "rewrite," which means to write something again. This pattern holds for many other verbs as well, indicating a sense of revisiting or repeating an action. Understanding the role of the prefix "re-" can help learners grasp the meaning of new words and how they relate to actions they may already know.
