Consider the following utterance from a child aged 4 years: "We went to the zoo and we sawed the lions, but they didn't roared very loud." This utterance is best described as belonging to which stage, and what specific linguistic phenomenon is demonstrated by "sawed"?

A transcript reveals a conversation between a father and his three-year-old daughter, Chloe.

Chloe: Look! Duckie swim!
Father: Yes, the duck is swimming in the pond.
Chloe: Duckie go splash!

(a) Identify the developmental stage Chloe is most likely in based on the linguistic evidence in the transcript.
(b) Explain two grammatical features of this stage present in Chloe's speech.
(c) Discuss the role of the father's response in relation to Bruner’s Language Acquisition Support System (LASS).

The Telegraphic stage is a crucial phase in child language acquisition.

(a) Describe the typical age range and the structural characteristics of utterances during this stage.
(b) Explain the concept of 'content words' versus 'function words,' and analyze why a child in the telegraphic stage predominantly uses one over the other.
(c) Provide two examples of original telegraphic utterances and explain how they demonstrate the child's developing understanding of syntax despite the omission of certain grammatical elements.
