What does unformed mean?
Unformed means not yet shaped, developed, or organized into a definite form. Its most characteristic use is biological: an unformed embryo is one that has not yet developed the structures and features associated with a later stage of development. More broadly, the adjective can describe a substance, idea, plan, or artistic work that lacks a settled organization or shape. In this extended use, it often suggests potential rather than complete disorder, because something unformed may still be capable of developing. The word is more formal and literary than familiar alternatives such as unfinished or incomplete, and it can carry a slightly technical or abstract tone. Unformed is also occasionally used of matter or material that has not been given a definite form. It should not be confused with informed, which concerns knowledge, or unfounded, which concerns the lack of evidence for a belief or claim.

Where does unformed come from?
English formed the adjective by attaching the negative prefix un- to formed. The prefix belongs to the native Germanic vocabulary of negation and is represented in Old English, while formed comes through French from Latin formare, meaning “to shape” or “to form.” The resulting adjective has long been used for both undeveloped organisms and matter or ideas lacking a definite structure.
How unformed is actually used
The word is relatively uncommon in everyday speech. It is especially associated with biological or developmental description, but it can also appear in formal and literary contexts when discussing ideas, materials, or plans that have not yet developed a clear structure.
