A language is a systematic means of communication by the use of sounds or conventional symbols. It is the code we all use to express ourselves and communicate to others. It is a communication by word of mouth. It is the mental faculty or power of vocal communication. It is a system for communicating ideas and feelings using sounds, gestures, signs or marks. Any means of communicating ideas, specifically, human speech, the expression of ideas by the voice and sounds articulated by the organs of the throat and mouth is a language. This is a system for communication. A language is the written and spoken methods of combining words to create meaning used by a particular group of people.
Language, so far as we know, is something specific to humans, that is to say it is the basic capacity that distinguishes humans from all other living beings. Language therefore remains potentially a communicative medium capable of expressing ideas and concepts as well as moods, feelings and attitudes.
A set of linguists who based their assumptions of language on psychology made claims that language is nothing but ‘habit formation’. According to them, language is learnt through use, through practice. In their view, ‘the more one is exposed to the use of language, the better one learns’.
