Here's why:
* Subject: The subject of a sentence is the person, place, or thing that performs the action.
* Predicate: The predicate of a sentence contains the verb and tells what the subject does or is.
Phrases are groups of related words that do not contain both a subject and a predicate. They can function as nouns, adjectives, adverbs, or other parts of speech.
Examples of phrases:
* "In the garden" (prepositional phrase) - This phrase describes a location but doesn't have a subject or verb.
* "Running quickly" (participial phrase) - This phrase describes an action but doesn't have a subject or verb.
* "To eat ice cream" (infinitive phrase) - This phrase describes an action but doesn't have a subject or verb.
Complete sentences contain both a subject and a predicate.
Example of a complete sentence:
* "The dog barked loudly." (Subject: "The dog"; Predicate: "barked loudly")
