Language delay refers to the inability to develop language skills at the expected rate. Children with language delay have limited vocabulary, difficulty understanding and expressing language, and poor grammar. Synonyms for language delay include speech delay, late language emergence, expressive language disorder, and developmental language disorder. Each term emphasizes different aspects of the condition, but they all reflect a delay in normal language development. Identifying language delay early and seeking appropriate intervention, such as speech therapy, can help children meet their developmental milestones and improve overall communication skills.
