If you haven’t seen this word before, you’re not alone. It’s a newly-coined term created by Citigroup’s Ebrahim Rahbari and first published in an informational paper authored by him and Citi Chief Economist Willem Buiter. It combines “Greek” or “Greece” with the word “exit” and refers to the possibility of Greece leaving the Eurozone. The word has been picked up by media worldwide and it may well worm its way into the official lexicon. And it certainly has Greek roots beyond the obvious “Gr” – the word “exit” itself comes from the Greek “exodos”, meaning “going out”.
