What is characterized by a child displaying hand movements and simple words to convey meaning?

Telegraphic speech is characterized by a child's ability to convey meaning using simple words, often leaving out less critical words like articles and prepositions. This form of speech is typically two to three words in length and conveys a complete thought, such as "want cookie" instead of "I want a cookie." Alongside this verbal communication, children often use hand movements to emphasize their message, adding a nonverbal component that enhances understanding.

Understanding telegraphic speech is crucial, as it reflects a child's developing linguistic abilities and cognitive skills. It signifies that the child is starting to grasp the rules of language and can express desires and needs more effectively than through babbling alone, which consists of repetitive consonant-vowel combinations without specific meaning. This developmental stage is significant in the study of language acquisition and the progression of communication skills during early childhood.
