Without a clear or fixed shape or form. It can describe physical objects or abstract things like plans or ideas that are not well organized.
From Greek *amorphos* (“shapeless”), from *a-* (“without”) and *morphē* (“form, shape”). The English adjective adds the suffix *-ous* to this root.
“Amorphous” literally means “without shape,” which is why we use it for blobs, clouds, and vague plans. It’s a useful word for anything that resists being pinned down—whether jelly, crowds, or half-formed dreams. Having a name for shapelessness makes it easier to notice.
