Brown's Stages of Syntactic and Morphological Development
Typical Expressive Language Development
"Brown's Stages" were identified by Roger Brown 1925-1997 and described in his classic book (Brown,1973).

The stages provide a framework within which to understand and predict the path that normal expressive language development usually takes, in terms of morphology and syntax.

Morphology
is the branch of grammar devoted to the study of the structure or forms of words, primarily through the use of the
morpheme
construct.
Syntax
is a traditional term for the study of the rules governing the combination of words to form sentences.
A morpheme is a unit of meaning.

SEND- 1 word = 1 unit of meaning
RESEND- 1 word = 2 units of meaning
Nomination that car That's a car
Recurrence more juice There is more juice
Negation-denial no soo soo I didn't do soo soo
Negation-rejection no more I don't want more
Negation-
non-existence birdie go The bird has gone
