Conjunctions join words, phrases, or clauses. Using them correctly creates clear, grammatically sound sentences. The Digital SAT tests your ability to choose the right conjunction and punctuate accordingly.
Core Concepts
Coordinating Conjunctions (FANBOYS)
For, And, Nor, But, Or, Yet, So
Join two independent clauses with a comma + FANBOYS:
"The experiment was long, but the results were worth it."
Subordinating Conjunctions
Although, because, since, while, if, when, after, before, unless, until, whereas...
Create a dependent clause that cannot stand alone:
"Although the weather was bad, the event continued."
"The event continued although the weather was bad."
(Comma after the dependent clause when it comes first; no comma when it comes second.)
Choosing the Right Conjunction
- Contrast: but, yet, although, however, whereas
- Cause: because, since, for
- Addition: and, also, moreover
- Condition: if, unless, provided that
Strategy Tips
Tip 1: Determine the Logical Relationship
Are the clauses contrasting, adding, explaining cause, or showing condition?
Tip 2: Match Punctuation to Conjunction Type
FANBOYS: comma before. Subordinating conjunction at the start: comma after the dependent clause.
Tip 3: Avoid Double Conjunctions
"Although it rained, but we went" is wrong. Use one conjunction, not two.
Key Takeaways
FANBOYS join independent clauses with a comma.
Subordinating conjunctions create dependent clauses.
Choose the conjunction that matches the logical relationship.
Comma placement depends on whether the dependent clause comes first.
Don't use two conjunctions for the same relationship.
