Bloody

From Old English blōdig ('covered in blood'), from blōd ('blood') + -ig (adjectival suffix). The intensifier usage, first attested in the 17th century, has a disputed origin. Three theories compete: (1) a corruption of 'by Our Lady' (a Marian oath); (2) an association with aristocratic rowdiness ('bloods' being young aristocrats); (3) simply an extension of the literal meaning as a violent intensifier. No single etymology has been definitively established.

The peculiar status of 'bloody' as a profanity is largely a phenomenon of British and Commonwealth English. In the 18th and 19th centuries, it was considered one of the most offensive words in polite British society. George Bernard Shaw caused a sensation when Eliza Doolittle said 'Not bloody likely' in Pygmalion (1914); the line was reported as a scandal in newspapers the following day. The Australian relationship with 'bloody' is even more intimate. The word appears in folk songs, political speeches, and casual conversation with such frequency that it has been called 'the great Australian adjective,' a title first bestowed by the Bulletin magazine in 1894.

Mild in contemporary British and Australian usage; effectively invisible in American English, where it carries no vulgar connotation whatsoever. The gap between its near-invisibility in the United States and its historical notoriety in Britain makes 'bloody' one of the most regionally asymmetric profanities in the English language.

The transatlantic divide is stark. American speakers frequently do not recognize 'bloody' as profanity at all, associating it with quaint Britishness rather than vulgarity. In Australia, 'bloody' is so embedded in casual speech that the 2006 Tourism Australia campaign 'So where the bloody hell are you?' was banned in the UK but celebrated domestically. In British English, the word has softened considerably since the Shaw era but remains mildly vulgar.
