ethereal

Something ethereal is airy and insubstantial, like a ghostly figure at the top of the stairs. This word can also describe something delicate and light, like a singer’s ethereal voice.

Ethereal comes from the Greek word for ether, which means “air” or more specifically “the upper regions of space.” An ethereal substance or sound is one that carries the feeling of light and air — something you might see in a vision that strikes you as heavenly or supernatural.
