Process
In anatomy, a process is a projection from a structure.
The process of the mandible is the part of the lower jaw that projects forward.
In a more general sense, a process is a series of actions or events that are part of a system or of a development, particularly one characterized by gradual changes that lead toward a particular result.
For example, there is the process of growth.
The word 'process' comes from the Latin <I>pro-</I>, forward + <I>ceder</I>, to go = to go forward.
