Child language acquisition

• Babbling includes simple vowel and consonant sounds or syllables that young infants produce.
• The child's first words are usually nouns, followed by verbs.
• By age two, children have an average vocabulary of about 200-350 words.
• Language development is influenced by factors such as genetics, environment, culture, and social interaction.
• The babbling stage is characterized by the production of repetitive, rhythmic vocalizations with no clear meaning.
• Children begin to understand the meaning of words at around six months old.
• Children begin to understand the meaning of grammatical morphemes (e.g., plural -s) around age three.
• Around age four, children can use more complex sentences with multiple clauses.
• Cognitive abilities play a role in language development, including the ability to understand cause and effect relationships and categorize objects based on their properties.
• At around six months old, babies start to imitate sounds they hear from their caregivers.
• Between eight and ten months, babies start to imitate speech sounds and repeat them back to their caregivers.
• This stage is called cooing and involves producing short, melodious sounds like "goo" and "gaa."
• Children start using telegraphic speech, which consists of simple sentences without function words like articles or prepositions, between ages one and two.
• Telegraphic speech gradually becomes more complex over time, with the addition of function words and longer phrases.
• Idiolect refers to the individual differences in how people speak within a particular dialect or variety of a language.
• By age three, most children have mastered the basics of syntax (grammar) and are able to produce longer, more complex sentences.
• Telegraphic speech allows children to communicate basic ideas but lacks grammatical structure.
• Babies begin to use gestures such as pointing at things they want or shaking their head to indicate no.
