Transition Punctuation and Placement
SAT Reading & WritingExpression of IdeasMedium
Separate transition logic from sentence-boundary punctuation.
What you need to know
- A conjunctive adverb does not by itself join two independent clauses.
- Between independent clauses, use a semicolon before however and a comma after it—or start a new sentence.
- Introductory transitions are usually followed by a comma.
- Transitions inserted mid-sentence may require two commas.
The AYLOTI method
- Identify whether text on each side is an independent clause.
- Choose legal boundary punctuation first.
- Place commas around the transition as required.
- Finally verify the transition’s logical meaning.

Common SAT traps
- Creating a comma splice before however.

- Fixing punctuation while ignoring a wrong logical relationship.
Quick check
