Example sentencesExamples
- Maxwell believed electromagnetic waves such as light to be vibrations in the ether.
- Similarly, it was believed, light waves needed the aether through which to travel.

Origin

Late Middle English: from Old French, or via Latin from Greek aithēr 'upper air', from the base of aithein 'burn, shine'. Originally the word denoted a substance believed to occupy space beyond the sphere of the moon. sense 3 arose in the mid 17th century and sense 1 in the mid 18th century.

This comes via Latin from Greek aithēr ‘upper air’, from the base of aithein ‘burn, shine’. Originally it meant a substance believed to occupy space beyond the sphere of the moon. It was then used, from the mid 17th century, as a name for the rarefied substance formerly believed to permeate all space, a sense behind ethereal (early 16th century). The use of a volatile liquid as an anaesthetic is found from the mid 18th century. Ethernet, a blend of ether and network dates from the 1970s.
