Language is a valuable means of communication. In effect, human beings are the only species capable of producing decipherable, meaningful and discreet sounds. Language thus means only human communication. It has other features too: it is a system and is symbolic. This is so because we can think and assimilate our thoughts into words and other linguistic units - sounds, syllables, words, connected speech, etc. No other living organism can think and speak as we do.
