When it comes to expressing the completion or termination of something, the word "to end" may seem like the most common and straightforward choice. However, there are plenty of other words and phrases that can be used as synonyms, adding variety and nuance to the way this concept is conveyed. Some possible alternatives include "to conclude," "to finish," "to culminate," "to wrap up," "to draw to a close," "to bring to a finale," "to terminate," "to close out," and "to wind up." Depending on the context and tone of the sentence, any of these options could be just as effective as "to end".
