nonergodic (English)

Where does "nonergodic" come from?

The English adjective 'nonergodic' is formed from the negative prefix 'non-' combined with 'ergodic'[1]. The word 'ergodic' itself stems from International Scientific Vocabulary components built on Ancient Greek roots, specifically 'ἔργον' meaning 'work' combined with either 'ὁδός' meaning 'way' or 'εἶδος' meaning 'image'[2]. The Greek root 'ἔργον' traces back through Proto-Hellenic '*wérgon' to the Proto-Indo-European root '*wérǵom'[3]. Meanwhile, 'ὁδός' descends from Proto-Hellenic '*hodós'[4], and 'εἶδος' derives from Proto-Hellenic '*wéidos' and the Proto-Indo-European root '*weyd-' meaning 'to see'[5].

Open questions

• The etymological origin of the component 'ergodic' is disputed between a combination involving 'ὁδός' and one involving 'εἶδος'. [2]
• The derivation of Proto-Hellenic '*hodós' from Proto-Indo-European '*sodós' and its connection to '*sed-' have been disputed. [4]
