The 1997 film Titanic is one of the most popular movies ever made. It won many film awards and was one of the highest-grossing films in movie history.

The film is a love story set against the sinking of the famous ship in 1912. It has many memorable scenes. Some of them can teach you important ideas about English grammar.

Today, we will explore one short scene to teach you about tag questions and polite forms of speaking. A tag question is a short question added to a statement.

#1 Tag questions

In our scene, Jack, played by actor Leonardo DiCaprio, eats dinner with a group of rich people. DiCaprio does not come from a wealthy background – just the opposite, in fact. He does not have a home.

A wealthy woman asks Jack a difficult question. She asks if he enjoys his homeless life.

You can hear the tense silence after her question.

"And you find that sort of rootless existence appealing, do you?"

"Well, yes, ma'am, I do."

Let's examine this short exchange.

We will begin with the woman's question.

The woman's question is a kind of tag question.

First, she makes a statement:

"And you find that sort of rootless existence appealing"

Notice that the main verb is find.

The woman follows the statement with a tag question:

"do you?"

If English speakers make a statement that uses a verb other than be, then the tag question often uses an auxiliary verb such as do or have. In this case, the woman made a statement using the verb find, and she used the auxiliary verb do in the tag question.
