Grammar guide: Linking clauses

A guide to linking clauses on the SAT.

What are clauses?

A clause is a series of words that contains a subject and a conjugated verb. There are two main types of clauses:
An independent clause can stand on its own as a complete sentence.
A dependent clause must be linked to an independent clause.
The SAT focuses on how clauses can be linked together (or kept apart). These conventions may be tested in Boundaries questions that you encounter on test day.

Linking clauses

There are several ways to link clauses. The SAT focuses on end of sentence punctuation, coordination, subordination, and semicolons.
Let's look at each in turn:

End of sentence punctuation

Using end punctuation (like a period or question mark) is the simplest way to separate clauses. You should be very familiar with using end punctuation in your own writing.
There are only two rules for end punctuation:
  1. The punctuation mark must match the function of the sentence it follows.
  2. End punctuation can only be used to separate two independent clauses.

Coordination

Coordination involves the linking of two independent clauses within a single sentence. To coordinate independent clauses, we must use two things:
  1. a comma (,)
  2. a coordinating conjunction
The only coordinating conjunctions in English are known as the FANBOYS (for, and, nor, but, or, yet, so).

Subordination

Subordination involves linking two clauses by making one of the clauses dependent. To subordinate an independent clause, we must use two things:
  1. a subordinating conjunction
  2. a comma (,)*
Subordinating conjunctions are words that turn an independent clause into a dependent clause. There are many subordinating conjunctions, but some examples include although, since, because, while, when, and after.
*Note: Some subordinating conjunctions can link clauses without a comma, but only if the dependent clause comes second.

Semicolons

Semicolons can be used to link two independent clauses without any conjunction.

How to identify linking clauses questions

When approaching boundaries questions, it's important to identify which Standard English conventions are being tested.
You may want to look for errors in linking clauses if
  • the choices add or remove commas and FANBOYS conjunctions
  • the choices add or remove end punctuation like periods or question marks
  • any choice contains a semicolon
If you don't see any of these features, then the question likely doesn't deal with linking clauses.
Let's look at a linking clauses question now:

Linking clauses example

In 2017, the couple converted a vacant lot in the city into an ______ in the years that followed they acquired nine additional lots and established more than 35 hives.

Top tips

Use the before and after test

When you see choices that offer a variety of punctuation options, check if what comes before and after the blank are independent clauses. If one side of the blank is not an independent clause, then you're likely dealing with a supplements or punctuation question (which focus on different rules).
