The quality or condition of being cyclical; the degree to which something exhibits cyclic or recurring patterns.
From 'cyclical' (cyclic plus -al) plus the abstract noun suffix '-ness' (Old English -nes). The '-ness' suffix is one of the oldest ways to create abstract nouns in English.
The cyclicalness of nature—how everything repeats in patterns—is what allowed ancient peoples without modern instruments to predict eclipses, plant crops, and navigate by stars.
