What Are Elliptical Structures?

There is an important part of grammar that is common in writing and everyday speech. But unlike many other subjects in grammar, this subject is defined¹ by what is not expressed.

What is this mysterious subject?

In today's report, we will explore elliptical structures.

Let's start with a few important terms and ideas.

Definition

Clauses³ are groups of words with a subject and a predicate.

When part of a clause² – generally part of the predicate - is left out but still understood, we get an elliptical clause.

Imagine you are watching an American television show. You hear the following:

Who is going to cook dinner?

I will.

In this case, the modal "will" appeared without a main verb. The complete statement is "I will cook dinner." The words "cook dinner" are understood between the speakers, although unspoken. This is a kind of elliptical clause.

Elliptical structures are a wonderful way to avoid repeating words. They can make your statements more natural or more complex. But they can also reduce clarity⁴ if used incorrectly.

The main problem with elliptical structures is that they depend on an absent part of a sentence being understood by the listener.

If parts of the sentence do not agree – for example, the subject and implied verb do not agree - then the sentence can become unclear.

Different kinds of elliptical structures

There are a few different kinds of elliptical structures - noun ellipsis⁵, verb ellipsis, and verb phrase ellipsis.

In a noun ellipsis, a noun is left out. In a verb ellipsis, a verb is left out. And in a verb phrase ellipsis, a verb phrase is left out.

You already learned about an example of a verb phrase ellipsis – our example about cooking dinner. The verb phrase "cook dinner" was not expressed. All that remained were the words "I will."

Elliptical structure #1

What about a verb ellipsis, one that does not have a modal such as "will" or "can"?

One common way a verb ellipsis appears is in sentences with two or more independent clauses. These clauses are joined by a semicolon.

Consider this example:

Tom took a train; Mary, a cab.

In this example, the verb in the second part of the sentence does not appear. This sentence replaces two statements:

Tom took a train.

Mary took a cab.

Since the same verb form - "took" - repeats between the two statements, you can join them with a semicolon and remove "took" from the second part of the sentence. That is how we arrive at

Tom took a train; Mary, a cab.

This structure could be used in everyday speech or in formal writing.

Question 1

Let's take some time to work with this idea.

Use the following nouns and verbs to make a sentence that uses an elliptical structure. You might have to add a few more short words such as the, a, or an.

John Sally order pizza sandwich

Pause the audio and think of your answer before continuing.

Here is one possible answer:

John ordered a sandwich; Sally, a pizza.

In this sentence, the past tense of the verb "order" does not appear in the second part of the sentence. This is because it is understood the same verb form appears in the first part of the sentence. If we were to pull apart the sentence into two separate statements, it would be the following:

John ordered a sandwich.

Sally ordered a pizza.

But instead of repeating the same verb, we joined the two statements into one sentence that has a semicolon and a comma. That is how we arrive at:

John ordered a sandwich; Sally, a pizza.

Question 2

Now let's try a different question. Use the following nouns, pronoun, and verb to make a sentence that uses an elliptical structure. You might have to add a few more short words such as the, a, or an.

We Bob prefer live music recordings⁶

Pause the audio and think of your answer before continuing.

This question was a trick question. You might think that the answer is this:

We prefer live music; Bob, recordings.

An elliptical structure might not be the best choice here.

The reason is because the verb "prefer" should be used in two different ways in the sentence. In the first part, "prefer" agrees with the subject, We. In the second part, the verb form "prefers" agrees with the subject, Bob. In other words, if we pulled apart the sentence into two separate statements, it would be something like this:

We prefer live music.

Bob prefers recordings.

So, we would have to use a different kind of sentence to express the idea. It could be, for example, "We prefer live music; Bob prefers live music."

Closing thoughts

The central idea in today's report is that elliptical structures suggest language but do not directly express it.
