Nonviolent Communication uses giraffe language
Nonviolent Communication (NVC) is an approach to communication that is claimed to be based on principles of nonviolence. It is not an attempt to end disagreements, but rather a method that is claimed to increase empathy and improve the quality of life of those who utilize the method and the people around them. Nonviolent Communication evolved from concepts used in person-centered therapy, and was developed by clinical psychologist Marshall Rosenberg beginning in the 1960s and 1970s. There are a large number of workshops and clinical materials about NVC, including Rosenberg's book Nonviolent Communication: A Language of Life.
 Marshall Rosenberg also taught NVC in a number of video lectures available online; the workshop recorded in San Francisco is the most well-known.NVC is a communication tool with the goal of first creating empathy in the conversation. The idea is that once there is empathy between the parties in the conversation, it will be much easier to talk about a solution which satisfies all parties' fundamental needs. The goal is interpersonal harmony and obtaining knowledge for future cooperation. Notable concepts include rejecting coercive forms of discourse, gathering facts through observing without evaluating, genuinely and concretely expressing feelings and needs, and formulating effective and empathetic requests. Nonviolent Communication is used as a clinical psychotherapy modality and it is also offered in workshops for the general public, particularly with regards to seeking harmony in relationships and at workplaces.Alternative names
In a recorded lecture, Marshall Rosenberg describes the origins of the name Nonviolent Communication. He explains that the name was chosen to connect his work to the word "nonviolence" that was used by the peace movement, thus showing the ambition to create peace on the planet. Meanwhile, Marshall did not  like that name since it described what NVC is not, rather than what NVC is. In fact, this goes against an important principle in the fourth component of NVC, i.e. requests. Specifically, in an NVC request, one should ask for what one does want, not what one doesn't want. Because of this, a number of alternative names have become common, most importantly giraffe language, compassionate communication or collaborative communication.
