Language is made up of socially shared rules that include the following:
- Form of Language
- Phonology is the sound system of a language and the rules about how sounds are combined.
- Morphology is the structure of words and how word forms are constructed.
- Syntax is the order and combination of words to form sentences.
- Content of Language
- Semantics is related to the meanings of words and sentences.
- Function of Language
- Pragmatics is the combination of language components (phonology, morphology, syntax, and semantics) in functional and socially appropriate ways.
When a person has trouble understanding others (receptive language), or sharing thoughts, ideas, and feelings completely (expressive language), then he or she has a language disorder.
