ASD can affect many areas of language including pragmatics, semantics, sytax/morphology, phonology, and comprehension.
Children with ASD can show problems with joint attention. In addition, they may have difficulty initiating and maintaining a conversation. They may not use communication for many functions. They have difficulty adapting to the conversational partner's style and needs.
They may have trouble with word retrieval and may respond inappropriately to questions.
They can have trouble with pronouns and verb enndings. In addition, they may have trouble constructing a sentence with a superficial term and may disregard the underlying meaning. They have less complex sentences than typically developing peers and may overrely on word order.
Phonology is the least impacted domain of language. They may have difficulties.
Children with ASD can have difficulty understanding connected discourse, such as conversations.
