Language
is the understanding of and ability to put together ideas to communicate.
That would include: what words mean, how to put words together and using words and phrases that are appropriate for any given situation. 1 in 20 children has symptoms of a language disorder. Language disorders are referred to as "receptive" (understanding words) or "expressive" (speaking words).
The causes of developmental language disorders are not known. They can occur in children with other developmental problems such as autism, hearing loss, or learning disabilities. A language disorder is different from a language delay in that the language skills do not develop normally. While the child may have some language skills, others are notably lacking. Or the way the skills are developing are atypical.Language disorders can occur with other types of developmental delays and are an integral in the diagnosis of autism in children.
