Generation

# First-Language Acquisition Stages Children progress through predictable stages of language acquisition: 1. **Pre-linguistic stage (0-12 months)**: Cooing and babbling with universal sounds that later narrow to native language phonemes 2. **One-word stage (12-18 months)**: Single words (holophrases) convey complete thoughts; vocabulary reaches ~50 words 3. **Two-word stage (18-24 months)**: Telegraphic speech emerges with simple word combinations following basic syntax 4. **Multi-word stage (2+ years)**: Rapid vocabulary expansion and grammatical complexity, with children generating novel, rule-based utterances **Key Formula**: **MLU (Mean Length of Utterance) = Total number of morphemes ÷ Number of utterances** — used to measure grammatical development, where MLU typically correlates with age (e.g., MLU of 1.0 at 18 months, 4.0+ by age 4).
