what is the difference between language and communication?

Answer 1

Even among linguists, there is no agreed upon definition of both, there have been different models around and still are.

However:
You could sum the difference up in a simple way by stating than language is a subset of communication: all language is communication, but not all communication is language. Communication means, information is transported (the so-called transfer-model of communication); language means, meaning is conveyed.

If you turn your car key in the ignition, information is "transported" to the engine - that would be mechanical communication. Animals, for instance, are said to have communication systems, but not "language" in the way most linguists would define it.

Communication (as a general model) is unambiguous, whereas with language, a lot depends on the circumstances and context: the same utterance can be understood in different ways in different contexts.

If you´re interested, I´d recommend Richard van de Lagemaats TOK coursebook, which gives a very easy-to-grasp, non-complex introduction into language and communication.

Answer 2

Language;
A language is considered to be a system of communicating with other people using sounds, symbols and words in expressing a meaning, idea or thought. This language can be used in many forms, primarily through oral and written communications as well as using expressions through body language.

Communication:
Is an act or instance of transmitting; information communicated; a verbal or written message; a process by which information is exchanged between individuals through a common system of symbols, signs, or behavior; verbal or written message, exchange of information, personal rapport.

Answer 3

Language is what we speak and we use language to communicate but communication is where you make a connection to another verbally, sign language, writing.

Answer 4

Simplistically, if I hit you on the head, I'm communicating to you that I am not happy with you. Likewise if I cry, you know I am unhappy. If I scowl at you, it should mean something. If you blow me a kiss, it also should mean something.

The above are all non-verbal communications - no language used.
