The history of today's word is not lost in the mists of time, although its history does get misty at points. "Nebula" comes to us from Latin, where it meant "mist" or "cloud." In its earliest English uses in the 1600s, "nebula" referred to a cloudy speck or film on the eye that caused vision problems. It was first applied to great interstellar clouds of gas and dust in the early 1700s. The adjective "nebulous" comes from the same Latin root as "nebula," but the first uses of "nebulous" don't appear in English until the late 1700s, well after the discovery of interstellar nebulae.
*Indicates the sense illustrated in the example sentence.
