specific language impairment
Definition - (Aka SLI)

A language-development disorder that can affect speech and understanding. It is described as a "pure" language impairment because it is not caused by other developmental hindrances, such as mental retardation, neurological damage, or hearing impairment.

1. People with SLI have problems combining speech sounds into meaningful units. For example, they tend to use short sentences and have problems saying and understanding syntactically complex sentences. They also have an impoverished vocabulary, word finding problems, and difficulty learning new words.
