Developmental language disorder (DLD) is a communication disorder that interferes with learning, understanding, and using language. These language difficulties are not explained by other conditions, such as hearing loss or autism, or by extenuating circumstances, such as lack of exposure to language. DLD can affect a child’s speaking, listening, reading, and writing. DLD has also been called specific language impairment, language delay, or developmental dysphasia. It is one of the most common developmental disorders, affecting approximately 1 in 14 children in kindergarten. The impact of DLD persists into adulthood
