* Subject: The subject is the person or thing performing the action. In this case, we don't know who or what "ran" – it's missing.
* Verb: The verb is the action word. Here, the verb is "ran."
* Predicate: The predicate is everything in the sentence that tells us about the subject. Since there's no subject, there's no predicate.
Therefore, "ran" is a simple verb phrase, not a subject, predicate, compound, or predicate.
To make a complete sentence, we need to add a subject:
* She ran. (Subject: She, Verb: ran)
* The dog ran. (Subject: The dog, Verb: ran)
