Meaning
A situation, question or field of activity that resists clear classification, where the rules are unclear or the boundary between right and wrong, legal and illegal, or one category and another is blurred. It is used of ethics, law, taxation, science and personal conduct alike. Neutral register; implies honest uncertainty or disputed classification rather than simple ignorance. Regional use: General English (spelled grey in UK usage, gray in US usage).
Origin
A twentieth-century coinage: the OED entry, first published in its September 2013 update, gives earliest evidence from 1935, in the journal Foreign Affairs. The metaphor needs no elaborate backstory; it extends the ancient use of grey for what lies between black and white, and the compound grey plus area also serves technical senses, such as an actual grey-toned region in a photograph. In British English the spelling is grey and in American English gray, but the figurative use is shared across both.
