Äther (German)
Where does "Äther" come from?
The German noun 'Äther' entered the language in the 16th century[1]. It traces its origins back to the Latin 'aethēr'[1], which itself was adopted from the Ancient Greek 'αἰθήρ' meaning 'sky' or 'ether'[2]. This Greek term derives from the verb 'αἴθω'[3], which stems from the Proto-Hellenic form '*áitʰō'[4]. Ultimately, the word is anchored in the Proto-Indo-European root '*h₂eydʰ-' which signifies 'burn' or 'fire'[4].
Open questions
- The reconstructed Proto-Hellenic form *áitʰō is an unattested derivation used to bridge the gap between Ancient Greek and Proto-Indo-European stages. [4]
