Amorphous means without a clearly defined form, like the moon's amorphous reflection in a lake. Figuratively, something amorphous lacks focus, be it a work of art, a political movement, or even someone's life plans.
The Greek roots of this word are clear: morphē means "form," and a- means "lacking or without." When creative works or ideas are described as amorphous, it means they suffer from a lack of organization. An amorphous object lacks a well-defined outline or structure, like amorphous jellyfish drifting on the surface of the ocean. And scientifically, this adjective simply describes something without a crystalline form, like an amorphous metal or amorphous ice.
