Inchoate

inchoate \in-ˈkō-ət\ adjective: being only partly in existence or operation; incipient (especially: imperfectly formed or formulated; formless, incoherent)

Etymology: Latin inchoatus, past participle of inchoare to start work on, perhaps from in- + cohum part of a yoke to which the beam of a plow is fitted

For a word that signifies the formless and incoherent, inchoate sure is hard-edged and rock-solid on the tongue.
