Protopathy: A word that doesn't exist, but I believe it should

from ergodic:

> 1. (mathematics, physics) Of or relating to certain systems that, given enough time, will eventually return to previously experienced state.

> 2. (statistics, engineering) Of or relating to a process in which every sequence or sample of sufficient size is equally representative of the whole.

+ -pathos

Ergo, ergopathy: Of or relating to certain emotional processes in which every sequence or sample, given enough time, cycles back to said previously experienced state. "Cyclical" or "circular" feelings.

These are the emotional cycles we've become accustomed to after learning through the motions a few times, usually during growth. It contains all the emotional processes that you can describe as "The known steps of <ergopathic object> are <loop steps>." Think about the common ergopathy of romantic relationships; of grief; of starting a new job; and leaving one; what you do on Sunday when you're down; how you speak to that friend to calm their nerves or cheer your kid up; where you prefer taking important calls… There is also the more rhythmic ergopathy of natural cycles, such as solar (24h and 365 days) and moon-related, that some individuals feel more keenly than others. There is a sense that, once you've been through enough of them, you've been through all of them reliably enough.
