Vocabulary growth
The expansion of a child's vocabulary from first words through early childhood. Vocabulary growth rates are rapid and follow predictable patterns.
Real World
Benedict's (1979) study found that children typically reach their first 50 words by around 13 months, but the next 50 words arrive far more quickly — mirroring how Netflix subscribers grew slowly at first, then exploded once the product was embedded in daily life.
Exam Focus
When 'assess' questions appear, quantify vocabulary growth with specific figures (e.g. 50 words by 18 months) to show accurate knowledge.
