It sounds posh, doesn’t it? But ‘scurrilous’ is actually the linguistic equivalent of getting slapped round the head with a rolled-up newspaper. It means ‘grossly or obscenely abusive’ or ‘slanderous’. So if you’re accused of making scurrilous claims, your pants are almost certainly in need of a visit from the fire brigade.
But how did such a fancy-sounding word end up doing such dirty work? Like lots of refined-but-rude words, ‘scurrilous’ comes to us from Latin. It traces back to ‘scurrilis’, which means ‘buffoon-like’ or ‘coarse’. And that comes from ‘scurra’, meaning ‘jester’ or ‘clown’ AKA someone who made a living making rude jokes (like previous star of the word of the week – and best job title evs – Roland the Farter).
Over time, ‘scurra’s association with low humour, insults and botty burps (sorry) stuck. So it wasn’t long before ‘scurrilous’ came to describe anything vulgar, mocking or abusive – especially in speech or writing.
Us English speakers got hold of ‘scurrilous’ in the 16th century. The earliest known printed use is in 1570 in the ‘Thesaurus Linguæ Romanæ & Britannicæ*’ by Thomas Cooper (theologian, Bishop of Winchester and master of Magdalen College at Oxford University): ‘Scurrilous iesting and vnshamefast rayling.’
Translation: rude jokes and shameless ranting – or in modern terms, social media.
*The full title of this is, deep breath, ‘Thesaurus Linguæ Romanæ & Britannicæ: tam Accurate Congestus, vt Nihil Penè in Eo Desyderari Possit, Quod Vel Latinè Complectatur Amplissimus Stephani Thesaurus, Vel Anglicè, Toties Aucta EliotæBibliotheca’. Phew. You can also read it online, if you have a spare six months or so, and a magnifying glass.
