Unformulated → It is formed from "un-" (meaning not) and "formulate" (from Latin "formulare", meaning to shape or form). The word "unformulated" means not shaped or not expressed in a specific form.
Think of 'not' ('un-') having a specific 'shape' or 'form' ('formulate') — that's why unformulated means something that hasn't been clearly defined or expressed.
