In one of my recent Weekly Word Watches for the Oxford Dictionaries blog, I highlighted bitcoin, the cryptocurrency whose valuation continues to skyrocket.
As I explain in the article, the bit in bitcoin – a coinage attributed to its mysterious creator(s) Satoshi Nakamoto in 2008 – was shortened from binary digit in 1948. Binary digits are those 1’s and 0’s that make our computers work.
And thanks to the success of bitcoin, other cryptocurrencies have also branded themselves as coins, such as Dogecoin and Peercoin, suggesting -coin is becoming a productive combining signifying a digital currency.
But what of the word coin itself? Its origins transports us back to some of the earliest days of writing.
