"That's a great deal to make one word mean," Alice said in a thoughtful tone. "When I make a word do a lot of work like that," said Humpty Dumpty, "I always pay it extra."

Nebulous

 
Nebulous means cloudy; lacking definite form or limits; hazy; vague or ill-defined.


It comes for the Greek word nebula which meant a cloud. Nowadays a nebula means an immense cloud of gas (mainly hydrogen) and dust in interstellar space. In early astronomy the word referred to almost any extended astronomical object (other than planets and comets).
