A shift is the process which occurs when the letters of one word are all shifted the same number of steps along the alphabet (looping from Z to A) to make another word. For example OHM + 1 = PIN, whilst CHEER + 7 = jolly. Here, I refer to these as basic shifts. This article examines other types of shift in which the shift values are not all the same but which abide by various rules. Each series of shift values makes a shift pattern.
