Numerology is any belief in the divine, mystical relationship between a number and one or more coinciding events. It is also the study of the numerical value of the letters in words, names and ideas. It is often associated with the paranormal, alongside astrology and similar divinatory arts.
Despite the long history of numerological ideas, the word "numerology" is not recorded in English before c.1907
The term numerologist can be used for those who place faith in numerical patterns and draw pseudo-scientific inferences from them, even if those people do not practice traditional numerology.
