College Composition / Unit 7 CMP 0153 short lesson, about 20 seconds
Commas After Introductory Elements
Captions available
The idea
Use a comma after an introductory word, phrase or clause that comes before the main clause.
In practice
"After class is over, we should review our notes"; "Shuffling his feet, he waited"; "However, nothing has changed."
Where people slip
A missing comma after a long introduction can make readers misread the subject.
