Language is a code for expressing and interpreting oral and written thoughts and needs.
Language is structured in hierarchical components that are interdependent. These components are phonology, morphology, syntax, semantics, and pragmatics. All of these components are critical in both oral communication and written communication. Oral communication involves the patterning of sounds to form words that are put together into sentences to communicate a meaningful message in different social contexts. Written communication involves conveying meaning by using appropriate lexical and syntactical features dictated by aspects such as audience, purpose, and structure.
