1. LANGUAGE DEVELOPME NT LANGUAGE IS A PROCESS THAT IS LEARNED IN EARLY HUMAN LIFE.

2. -Language is a complex cognitive skills. -Human language is characterized by a complex organization. -Approx 4,000 Human Language is grouped into about 50 language families. -All these languages share a basic structure, involving a set of sounds and rules for combining sounds to produce meanings. -Infant starts without language, yet by 10 months of age, babies can distinguish speech sounds and engage in babbling.

3. -Each language have grammar and phonological rules which indicates how phonemes can be combined to produce speech sounds. Phonemes are combined together to create morphemes-then it progresses into phrases, then it forms sentences also refer to syntactical rules. -Phonemes: is the smallest unit of sound that is recognizable as speech rather than as random noises and makes understandable words. For ex: /t/ sound in the words tip, stand, water, cat. -Morphemes: are smallest meaningful unit of languages-conveys meaning. For ex: work-ing or like-ly are 2 morpheme, has meaning. -Syntactical rules: rules used to describe how things are organized or ordered.

4. All languages have grammar rules that generally fall in 2 categories: 1. Morphological rules indicates how morphemes can be combined to form words. They are refer to things and events. For ex: CAT, DOG, BIRD, CAR, etc. -content morpheme Then there’s words like WHEN, AND, OR, BUT which are function morpheme that ties sentence together. 2.Syntactical rule indicates how words can be combined to form a sentence.

5. Here’s an example of sentence structure: Example: Th e b o i h i t th e b o l Morpheme: The-boy-hit-the-ball. Turns into phrase: The-boy hit-the-ball. Sentence: The boy hit the ball.

6. Language development by Ages: Ages: Language Milestones: 0-4 mos.> cooing (phonemes) 4-6mos.> babbling (consonants), deaf babies begins to babbles with their hands 6-10mos.> understanding some words like simple request (drink milk, bring bottle) 10-12 mos.> start using single words (momma, bottle, car, toy, etc) 12-18 mos. > learning up to 30-50 single words 18-24 mos. > start two-word phrases and vocabulary, 50-200 words & understanding rules 2-3 yrs old> Vocabulary of 1,000 words and speaks in complete sentences 3-4 yrs old> Vocabulary grows more than 10,000 words, forming full sentences, can form questions and negotiate.

7. 3 Characteristics of Language Development 1.Children learned at an astonishly rapid rate 2.Children make few errors while learning to speak. 3.Children passive mastery (deep structure) of language develops faster than their active mastery. (Deep structure refers to the meaning of a sentence.) (This is also the test question. )
