Comma After Introductory Elements
A comma is used to separate introductory words, phrases, or clauses from the main clause of a sentence to improve readability and clarity.
- Applies to introductory words (e.g., 'Yes,' 'Well,')
- Applies to introductory phrases (e.g., 'In the morning,')
- Applies to introductory dependent clauses (e.g., 'Because it was raining,')
- Short introductory phrases (3-4 words) are often optional, but generally recommended for clarity.
Memory trick: Commas are like stop signs for clarity.
