Which term best describes vocabulary growth in early childhood?

• A. Lexical Development (Vocabulary Growth)
• B. Phonemic Development
• C. Pragmatic Development
• D. Syntax Development

Answer: (A)

Vocabulary growth in early childhood is captured by lexical development, which refers to expanding the child’s store of words and word meanings. This area covers both receptive vocabulary (words the child understands) and expressive vocabulary (words the child uses to communicate). Children build their lexicon through exposure to language, labels, conversations, and experiences, often rapidly adding new words and connecting them to concepts.

Phonemic development focuses on the sounds of language—the phonemes and how they are produced and heard. Pragmatic development deals with how language is used in social contexts, such as taking turns, staying on topic, and responding appropriately. Syntax development concerns grammar and how words are arranged to form sentences.

Because this question centers on growing the number of words a child knows and uses, lexical development is the best descriptor.
