Mechanisms of child language development[edit] Language serves the purpose of communication to express oneself though a systematic and traditional use of sounds, signs, or written symbols.[1] There are four subcomponents in which the child must attain in order to acquire language competence. They include phonology, lexicon, morphology and syntax, and pragmatics.[2] These subcomponents of language development are combined to form the components of language, which are sociolinguistics and literacy.[1] Currently, there is no single accepted theory of language acquisition but various explanations of language development have been accumulated.

Phonology
Phonology is concerned with the sounds of language. It is the function, behavior, and organization of sounds as linguistic items. Phonology considers what the sounds of language are and what are the rules for combining sounds. Certain sound combinations are allowed but other combinations are impossible. Phonology also encompasses variations in pronunciation. It will explain patterns in the pronunciation of words.

Phonetics is a closely related discipline of phonology. Phonetics provides us a description of how speech sounds in any language are produced by various organs of the body (articulation) and a description of the sound waves (acoustics). It is the concrete measurable physical properties of cognitive speech sounds-physical sound. Consonants are produced by impeding a stream of air from the lings as it passes through the throat, setting up waves of disturbance in the air that are heard as sounds. Vowels are produced by air expelled from the lungs flowing through the vocal cords and then passing freely through the mouth. If the vocal cords are stretched with the right tension they vibrate as air passes through them, causing sound waves. These sound waves can be manipulative by the height and location of the tongue. Particular variations of this sound are grouped into phonemes, or speech units. They are the categories of sound that function to signal differences in the words in language. Phonemes are words that differ by only one sound but have different meanings, such as pin and bin. Phonological acquisition in children can be measured by accuracy and frequency of production of various vowels and consonants, the acquisition of phonemic contrasts and distinctive features, or by viewing development in regular stages in their own speech sound systems and to characterize systematic strategies they adopt.

Semantics
The main ideas of semantics are the propositional function, the operation definition, the predictive value as criterion of truth and the theory of types. It is the branch of linguistics used to derive meaning or to signify.

Lexicon
The lexicon can be viewed as a very large and complex dictionary of words, enabling language speakers to use those words in speech production and comprehension. Lexicon is the inventory of a language's morphemes. Morphemes are a minimal meaning-bearing element or a building block of something in language that makes sense. For example, in the word cats, the component cat makes sense as does at, but at does not mean the same thing as cat. While ca, do not mean anything. Morphemes are composed of lexical formatives, words like cat; grammatical formatives, things like suffixes -s; and derivational affixes, thinks like un- or -ness It is the acquisition of the meanings of words for objects, actions, etc.

Morphology
Morphology is the study of form or forms. It is the mental system involved in word formation or to the branch of linguistics that deals with words, their internal structure and how they are formed. Morphemes are the smallest linguistic pieces with grammatical function.

Pragmatics
Pragmatics is the study of the relationships between linguistic forms and the users of those forms. The use of utterance to serve different functions. The ability to communicate one's feelings and desires and to pass on information the world to others.
