What is structure of sentence?

• The subject is usually a noun or pronoun that the sentence is about.
• The predicate contains the verb and tells what the subject does or is.

There are four basic sentence structures:

1. Simple sentence: Contains one independent clause (e.g., "The dog barked.").
2. Compound sentence: Contains two or more independent clauses joined by a coordinating conjunction (e.g., "The dog barked, and the cat ran.").
3. Complex sentence: Contains one independent clause and at least one dependent clause (e.g., "The dog barked because it was scared.").
4. Compound-complex sentence: Contains two or more independent clauses and at least one dependent clause (e.g., "The dog barked because it was scared, and the cat ran away.").
