Inchoate

Some really interesting etymology here:

Inchoate derives from inchoare, which means “to start work on” in Latin but translates literally as “to hitch up.” Inchoare was formed from the prefix in- and the noun cohum, which refers to the part of a yoke to which the beam of a plow is fitted. The concept of implementing this initial step toward the larger task of plowing a field can help provide a clearer understanding of inchoate, an adjective used to describe the imperfect form of something (such as a plan or idea) in its early stages of development. Perhaps because it looks a little like the word chaos (although the two aren’t closely related), inchoate now not only implies the formlessness that often marks beginnings but also the confusion caused by chaos.

I too thought it was somehow related to “chaos.”
