Telegraphic speech is a characteristic of child language where children produce utterances that are short and lack grammatical morphemes, such as articles and prepositions.

The environment plays a crucial role in language acquisition by providing children with input and feedback, shaping their language learning strategies, and influencing their motivation to learn language.

Speech perception is a prerequisite for speech production because children need to be able to perceive speech sounds in order to produce them correctly.

Phonology is the study of the mental representation of speech sounds, while phonetics is the study of the production and perception of speech sounds.

Metathesis is a morphological process, not a phonological process.

Simplification is the process by which children simplify adult speech by reducing the number of sounds or syllables in a word.

Use of complex sentences is not a characteristic of child speech. Children typically use simple sentences with few grammatical morphemes.

Semantic mapping is the process by which children learn to associate sounds with meanings.

Age is not a factor that influences the rate of language acquisition. Children typically acquire language at a similar rate, regardless of their age.

Articulation is the process by which children learn to produce speech sounds correctly.

Metathesis is a morphological error, not a speech sound error.

Pragmatics is the process by which children learn to use language in social contexts.

Language universals are not learned. They are innate.

Syntax is the process by which children learn to combine words into sentences.

Nouns are not grammatical morphemes. They are lexical morphemes.
