Stochastic

Stochastic is a word whose meaning is veiled for me

I've looked it up before, but it does no good

I know the definition will never "stick"

I imagine it as something thick, dark, and mysterious

Legerdemain as well, it might be the protocol for an arcane ritual?

Are these really even words, or the product of my own dreams?

Others know words, their meaning and origins

I must be content with their penumbra
