Hello! I'm Elizabeth O'Brien, and my goal is to get you jazzed about grammar. 

The Interrogative Sentence

An interrogative sentence asks a question, and it always ends with a question mark.

The subjects of questions can be a little tricky to find because they typically come after the verb or between parts of the verb phrase.

Would you like coffee?

Where are the brownies?

Did you buy eggs today?

Have you brushed your teeth yet?

Finding the Subject of An Interrogative Sentence

The good news is that you can rewrite questions in order to make the subjects easy to find! Yay!

How are you going to do this? You will change the question into a statement, and then the subject will be staring you in the face.



The subjects are underlined.
Is your house ready for visitors?Your house is ready for visitors.
Have you brushed your teeth today?You have brushed your teeth today.
Is this your jacket?This is your jacket.

Strange But True

Sometimes questions sound funny when we turn them into statements. This is particularly true for questions that start with who, what, where, when, why and how. Sometimes the words who or what are the subjects.



The subjects are underlined.
Where is your house?Your house is where.
When did you brush your teeth?You did brush your teeth when.
How do I zip your jacket?I do zip your jacket how.
Who is cooking the brownies?Who is cooking the brownies.
What was your name?What was your name.

How To Diagram Questions

Sentence diagrams are a way for us to SHOW how the words in sentences are related. We show these relationships without using any punctuation. Because of this, you will not see the question mark in a diagram of a question!

All sentences must contain a subject and a verb. Check out the diagrams below. On the left, you'll see a basic diagram of a subject and a verb. On the right, you'll see a sentence diagram for the question below.

Have you been cooking?
