whats a sentences for they've?

They've gone to see a movie that I have not seen

A sentence using "they've" could be:

"They've been working on their project all day."

To explain how to form this sentence, let's break it down:

1. Subject: "They" refers to more than one person or a group of people.
2. Contraction: "They've" is a contraction of "they have." It combines the subject "they" with the auxiliary verb "have."

Since the sentence is about a group of people, we use the third-person plural pronoun "they." To create the contraction, replace "have" with "they've" to indicate an action or state that the group has performed or experienced.

In this example, the sentence suggests that the group has been working on a project for the entire day.
