You and your doctor should carefully watch your child's progress into the school-aged years. Language is a system of verbal, written, or gestured symbols that are used to communicate. Language has several parts that develop at the same time. Language is divided into content, form, and use. Content, or semantics, refers to the meaning of the message.
Form includes grammar and syntax.
Grammar and syntax refer to rules that define the structure and organization of words to form sentences. Use refers to the use of language both verbal and nonverbal. An expressive language disorder means you have trouble using content, form, or use of language when trying to convey a message. Speech is the actual sound of spoken language. Articulation is making sounds.
