Whats the difference between a simple and a complex sentence?

Sure, here's the difference between a simple and a complex sentence:

Simple Sentence:

• A single independent clause.
• Contains a subject and a predicate.
• Example: "The dog barked."

Complex Sentence:

• A sentence that contains one or more independent clauses.
• Contains a subject, a predicate, and one or more modifiers.
• Example: "The dog barked at the mailman."

Independent Clause:

• A clause that contains a subject and a predicate.
• A clause that can stand alone as a sentence.
• Example: "The dog barked."

Modifier:

• A word that modifies a noun or pronoun.
• Can be adjectives, adverbs, or other modifiers.
• Example: "The dog barked loudly."

Additional Points:

• A complex sentence can be a simple sentence if it contains a single independent clause.
• A simple sentence can contain a complex sentence as a part of its structure.
• Complex sentences are more complex and require more grammatical analysis.
