Overview:
Language acquisition is the natural process by which humans learn language, particularly the way infants and young children acquire their first language. This process involves rapidly learning the sounds (phonology), words (vocabulary), and grammar (syntax) of a language through exposure and interaction, without formal instruction. Typically, children achieve major milestones in predictable stages: for instance, babbling in infancy leads to first words around 12 months, then two-word combinations and early sentences by age 2, and by around age 3–4 they have mastered the basic structure of their native language. SLPs study language acquisition to understand what “normal” language development looks like, which in turn helps them identify language delays or disorders early and guide interventions that support a child’s communication development in a linguistically rich environment.
