This document discusses the concepts of language and communication. It defines language as an abstract system of symbols that carry prescribed meanings, which can be sounds or letters. The key characteristics of language are that it is humane, meaningful, symbolic, systematic, and flexible. Communication is defined as the process of sharing information, messages, knowledge, or feelings through a communicator, message, channel, and receiver. The relationship between language and communication is that language provides one of the primary channels for the process of communication between humans. While communication is possible without language through gestures, language helps to make communication more meaningful, reduces confusion, and facilitates thinking, aesthetic expression, and cultural exchange.
