Gree language was spoken by the Gree, one of the oldest species in the galaxy. This language would make broad use of metaphors based on geometry and colors. In 3643 BBY, during the Old Republic era, a delegation of Gree droids present on Coruscant would speak in Basic while using Gree language patterns, which hindered communication with other beings. To outsiders, it would look as if they used the very same words to mean entirely different things.
