質問: なぜcurrencyには通貨という意味があるのですか?
回答: 「走る」という意味のラテン語動詞 cirrere の 現在分詞形 currens に由来するそうです。 currency (n.) 1650s, "condition of flowing," a sense now rare or obsolete, from Latin currens, present participle of currere "to run" (from PIE root *kers- "to run"). The notion of "state or fact of flowing from person to person" led to the senses "continuity in public knowledge" (1722) and "that which is current as a medium of exchange, money" (1729). ). 通貨は社会の中を走り回るからでしょう。
