Make parallel is a term used in engineering and construction to describe the process of aligning two or more objects in a straight line. Aligning, which has five letters, is the process of adjusting the position of an object so that it is in line with another object. Collimating, which has nine letters, is the process of adjusting the angle of an object so that it is parallel with another object. Together, these two processes are used to make parallel two or more objects.
