The Study of Language: Language: is primarily a means of communicating thoughts from one person to another. The Origins of Language While it is sure is that - unsurprisingly - spoken language developed long before written language, no-one knows for certain how language originated. There are, however, lots of speculations about the origin of human language. The Divine Source The Natural Sounds Source The Oral-Gesture Source Physiological Adaptation Interaction and transaction. The Divine Source According to one view God created Adam and " whatsoever Adam called every living creature , that was the name thereof " من ذلك .In most religions there appears to be a divine source that provides humans with language. However it seems that children with no access to human speech simply grow up with no language at all NO SPEECH = NO LANGUAGE. The Natural Sounds Source 1-'Bow-wow theory" one speculation on the origin of language is that the first words were imitations of natural sounds. It is true that there are onomatopoeic words in every language, i.e. words that echo natural sounds, for example: CUCKOO, SPLASH, BANG قرع, RATTLE خشخشة, BUZZ أزيز, etc. but language is not simply a set of words used as 'names'. 2- Another idea is that the original sounds of language came from' Natural cries of emotion', i.e. pain, anger and joy, for example: OUCH! 3-One another is the "yo-heave-ho theory" places the development of human language in a social context and states that language originated in the need to coordinate physical effort-grunts, groans, swear words. The Oral-Gesture Sourceإيماء Many of our physical gestures, using body hands and face, are means of nonverbal communication and are used by modern humans, even with their developed linguistic skills. The "oral-gesture theory" proposes an extremely specific connection between physical and oral gesture involving a "specialized pantomime فن التمثيل اإليمائىof the tongue and lips". Physiological Adaptation Some of the physical aspects of humans that make the production of speech possible or easier are not shared with other creatures: Human teeth are upright and roughly even in height. Human lips have an intricate muscle interlacing. The human mouth is relatively small, can be opened and closed rapidly and contains a very flexible tongue. The human larynx ( حنجرةor 'voice box') is special as well as the pharynx above the vocal cords can act as a resonator for any sounds produced. The human brain is lateralized and has specialized functions in each of the two hemispheres. The functions that are analytic, such as tool-using and language, are largely confined to the left hemisphere of the brain for most humans. All languages require the organizing and combining of sounds or signs in specific constructions. Interaction and transactional Many of the speculations on the origin of language deal with the question of how humans started to interact with each other. However there are two major functions of language use: The interaction function has to do with how humans use language to interact with each other socially or emotionally. The transactional function has to do with communicating knowledge, skills and information. This transactional function will have developed, in part, for the transfer of knowledge from one generation to the next. And while there are cultures that rely mainly on their oral tradition, in many cases, as speech by its nature is transient عابر, زائل, the desire for a more permanent record must have developed:
