Sentence structure is the order of all the parts in a sentence: subject, predicate, objects, phrases, punctuation, etc. It deals a lot with independent and dependent clauses and how they combine (explained below), the placement of words and phrases next to what they modify, as well as the use of proper grammar.

A sentence is a unit of grammar. Generally, sentences begin with a capital letter and end with a full stop, an exclamation mark or a question mark. In English grammar, a sentence must contain at least one main clause. English sentences can be simple, compound or complex.

In English grammar, sentence structure is the arrangement of words, phrases, and clauses in a sentence. The grammatical function or meaning of a sentence is dependent on this structural organization, which is also called syntax or syntactic structure.

A simple sentence is a sentence with just one independent clause (also called a main clause): Judy laughed. A compound sentence contains at least two independent clauses: Judy laughed and Jimmy cried. A complex sentence contains an independent clause and at least one dependent clause: Jimmy cried when Judy laughed.
