Final answer:
To diagram the sentence, you would identify the subject, verb, and prepositional phrase.
Step-by-step explanation:
To diagram the sentence, "Paul wanted to preach to the Christians at Rome", you would start by identifying the main subject and verb. In this case, the subject is 'Paul' and the verb is 'wanted to preach'. The prepositional phrase 'to the Christians at Rome' acts as the object of the verb and provides additional information about the direct object, 'preach'.
Diagram:
- Paul
- wanted to preach
- to the Christians at Rome
