Etymology: Greek mathematicians and poets used "khiliás" for the number one thousand, but the word could also stand for any vast quantity, and the Greek idea of a "thousand" was itself flexible. The Greek base "khī́lioi" means "one thousand," and the suffix "-ás" turns a number into a collective noun, so the word literally names a set of one thousand things. Latin borrowed it as "chilias," which carried the same sense of a group of a thousand. English took the word more directly than most number terms, and it still means exactly one thousand items, a grouping rather than a unit. Its near-relative "millennium" follows the same logic: "mille" in Latin is the thousand, and "annus" supplies the years. Both words show how European languages built names for large counts out of the basic number terms, though "chiliad" stayed a specialist word that rarely appears outside writing about numbers, poetry, or ancient Greek.
