Punctuating prepositional phrases: • We generally do not put a comma after a single short introductory prepositional phrase, but we do put a comma after a long introductory prepositional phrase or after multiple introductory prepositional phrases. From the beginning Churchill suspected Stalin. Like the nation’s true leader, Churchill was blunt. From the start of the war, Churchill suspected Stalin.
Avoid splitting the subject and verb: • The clearest sentences often have the verbs next to the subject, so it is often advisable to avoid putting the prepositional phrase between the two.
