nebulous
UK: ˈnɛbjʊləs | US: ˈnɛbjələs
adj. unclear, vague, or hazy in form or meaning
adj. relating to or resembling a nebula (astronomy)
The word "nebulous" originates from the Latin "nebula," meaning "cloud" or "mist." The suffix "-ous" (from Latin "-osus") denotes "full of" or "having the quality of." Thus, "nebulous" literally means "cloud-like" or "full of mist," reflecting its modern sense of vagueness or lack of clarity. The astronomical usage directly references the appearance of nebulae—diffuse clouds of gas and dust in space.
