Declarative sentences make statements without questions or strong emotion. They always end with a period and are the most common sentence type. Examples include "I am an expert in French cheese" and "London is the capital of England"
There are four main sentence structures: Simple, Compound, Complex, and Compound-Complex. A clause contains a subject and verb and forms a complete thought. Independent clauses are complete thoughts, while dependent clauses need independent clauses
Simple sentences contain only one clause. Complex sentences have one main clause and one or more subordinate clauses. Compound sentences have two or more clauses of equal rank
Simple sentences use 'be' verb with subject and simple adjective. Adjective sentences describe subjects without 'a/an' or changing form. Adjective + noun sentences combine 'be' with adjective before noun. Prepositional phrases indicate location using 'a/an' or 'the'. Other verbs express actions or thoughts
Main clause is a group of words that forms the major part of a sentence. Must contain a subject and verb to form. Can stand alone as a complete sentence
Simple sentences contain one main clause and can be phrases or clauses. Compound sentences have at least two main clauses joined by coordinating conjunctions. Complex sentences consist of main clause and subordinate clause joined by subordinating or correlative conjunctions
