Language

Language is considered a system of communicating with other people by using sounds, symbols and words in expressing a meaning, idea or thought. Language can be used in different forms, including oral and written communication, and expression through body language. Language can be broken down into three parts: receptive language, expressive language, and pragmatic (social) language.

RECEPTIVE LANGUAGE is the ability to comprehend information through both spoken and written form. It may include the understanding of vocabulary, concepts, and oral directions, as well as an individual's ability to sequence and recall information provided verbally and/or through text.

AN INDIVIDUAL WITH A RECEPTIVE LANGUAGE PROBLEM MAY:

• Have difficulty following directions
• Have decreased comprehension of "yes/no" and "wh" questions
• Have limited understanding of vocabulary
• Have poor understanding of grammatical markers (i.e., verb tenses, possessives) and syntax

EXPRESSIVE LANGUAGE is the ability to express oneself. This usually refers to language expression through speech, however, it also includes gestures, sign language, use of a communication board, written language, and other forms of expression used to communicate with others.

AN INDIVIDUAL WITH AN EXPRESSIVE LANGUAGE PROBLEM MAY:

• Have limited vocabulary skills
• Have deficits in expressive grammar (e.g., use of plurals, verbs, pronouns)
• Have difficulty forming clear thought and complete sentences

PRAGMATIC LANGUAGE refers to the rules of social language that encompass using appropriate language, changing language to meet the needs of the listener, and following the rules of conversation and storytelling.
