What is Sentence Types?
Within English, which covers grammar, vocabulary, reading, writing, poetry, drama and the skills for clear communication, this topic explains Sentence Types. English topics help you read closely and write with purpose, so each one here explains a skill and shows how it works in a model text.

Sentence Types in detail
Sentences are classified by structure. A simple sentence has one independent clause ("The sun rose"). A compound sentence joins two independent clauses with a conjunction or semicolon ("The sun rose, and the birds sang"). A complex sentence has an independent clause and at least one subordinate clause ("When the sun rose, the birds sang").
A compound-complex sentence combines both. Mixing sentence types makes writing varied and rhythmic: short sentences give impact and longer ones carry detail. Knowing the structures helps you punctuate correctly and control the pace and emphasis of what you write.
