language reflection

Animals and even plants can communicate between them, they can warn others of a threat. The human language uses a system of symbols and sounds,  with an given meaning. This symbols let us have better interaction, cause every thing has it own sound recognizable for everyone and, no't only a bark.There is a need to have a word for everything, that's why there are new words constantly appearing.

 Some meaning of words can be so powerful that makes as angry or happy.
