Quick Summary

Language acquisition is the process by which infants learn to understand and speak a language. This typically begins after their first birthday, with significant progress made by age two. Language involves comprehending words and sentences, and expressing thoughts and feelings. Infants first learn basic sounds (phonemes), then combine them into words. By 18 months, a child might have a vocabulary of about 50 words, often used to represent entire sentences. By age three, children typically use three-word combinations and understand more complex language structures. This innate ability to acquire language is a hallmark of human development, influenced by both biological factors and social interaction.1234
