nebulous
Lacking clear form
Nebulous means hazy, vague, or lacking definite form.
A nebulous idea hasn't been worked out clearly.
Nebulous plans remain uncertain.
The word comes from the Latin for cloud or mist, and that atmospheric quality persists—something nebulous has indistinct edges, whether it's a concept, a memory, or a promise: His intentions remained nebulous.
