y·lem

Etymologie

() Resuscitation of Middle English ylem, one of several variants for the Medieval Latin hyle (“matter”), a transliteration of Aristotle’s concept of “(fundamental) matter”, in Ancient Greek ὕλη (hulē, “wood(s), material(s), matter, subject”) or πρώτη ὕλη (“fundamental matter”). First known to have been used in modern English by George Gamow in a paper coauthored with Alpher and Bethe titled "The Origin of Chemical Elements", published in Physical Review, April 1st, 1948. Note: Claimed to have been found by Robert Herman in a large dictionary. In an interview Gamow also associated ylem with a Hebrew word, which should have been ילם (substantive “blind”), similar in pronunciation and appropriate for the hypothetical darkness of ylem.
