Developent of language

•  Phonology
•  Describes the sounds of specific languages, how they are produced, pronounced, every language has its own phonemes,which allow us to classify the sounds according to their structural basis: vowels, consonants; the latter being divided into bilabial consonants /p; b; m/, labiodentals /f; v/, dentals /t ; d; n; s; z; 1; r/, palatal consonants (tongue against the hard palate) /sj, zj/ is in <>; velar consonants (the back of the tongue is lifted towards the soft palate /k; g; ng; ch/ as in the English <>) the laryngeal/h.

• Semantics: study of the words, the lexicon, it is the study of words as such and their interrelationships (a.g. aride, to ride; right; open the door; and open mind)

• Syntaxis and Morphology: study of building clauses and their relationships in sentences; the relationships between parts of a clause changes in words,e.g to live, he lived, he is living; life, lively. Also <> e.g., speak, speech, speaker; baker, bakery, baking.

•  Pragmatic: the use of language in daily life:...linguistic competence; visual supportive elements.

• Metalinguistics: self-correction; grammatical reflection; new meanings of words.

Moreover, the spontaneous visual language of the deaf is of a totally differet sort of that of the oral system take the being visually situated in space of sign language in contrast with the succesisve course in time of the oral language. Elements here are: rhythm, simultaneity, emphasis.

Language System

Some facets of normal language development. They are to be known in order to understand the specific difficulties of language acquirement among deaf people.


A.. Like all other children, deaf children produce sounds as part of their total motor activity. 
B. There is a growth in specific language sounds.
C. Hearing becomes listening, anologous to the parallel development of <> into <>. the <> occurs very early in a hearing child. a relationship to the environment is created based on perceiving noises and sounds, especially the human voice. This is called << auditive feedback>>.
Severely deaf children reproduce sounds that are foreign to language. It is an indication for the child's milieu that its hearing is dysfuctional.

D. After the initial <> period follows the development of a language system.
