“Mommy is big” vs. “Mommy’s big” demonstrates the difference between:
Uncontractible and contractible copula

A child says, “Mommy cup.” This is an example of:
Inflectional overgeneralization
Possessive –’s omission (Stage II pattern)

stage ll
Stage l
Brown’s Stage V represents an MLU of approximately:

Stage l
Brown’s Stages I–V cover roughly what age range?
Birth – 2 years
1.5 – 4 years
3 – 7 years
