2. Identifying Prepositional phrases
• Prepositional phrases tell when or where. Commas will follow the
prepositional phrase to separate the ideas as one being introductory
and the other being the main idea.
• Please stay tuned for the following message from our sponsors
4. All the passengers aboard the runaway train were
frightened.
• This prepositional phrase answers the question of where.
• The passengers are on the runway train.
5. All rooms below deck are for sleeping.
• This prepositional phrase answers the question of where.
• This tells where the rooms are located.
6. The clues within the first few chapters will lead to
the murderer.
• This prepositional phrase answers the question of when.
• This tells where the clues where given
7. I will not obey the voices in my head.
• This prepositional phrase answers the question of where.
• This informs us that the voices exist in my head.
8. “When Sarah Winchester passed, the house had
160 rooms.”
• “when Sarah Winchester passed,” is the prepositional phrase because
it answers the question of when. It is when she passed or died.
• “the house had 160 rooms.” Is the main idea because Sarah's house
had 160 rooms after she passed.
9. When Sarah Winchester passed the house
had 160 room.
• This would be wrong because without the comma the sentence
changes to talking about Sarah passing a house.
