Isopsephy

Numerological connection between words whose letters' number values have equal sums

In numerology, isopsephy or isopsephism is the practice of adding up the number values of the letters in a word to form a single number. The total number is then used as a metaphorical bridge to other words evaluating the equal number, which satisfies isos or "equal" in the term. Ancient Greeks used counting boards for numerical calculation and accounting, with a counter generically called psephos ('pebble'), analogous to the Latin word calculus, from which the English calculate is derived.
