If something rankles, it irritates you in a way that really gets under your skin. Like neighbours who leave their bins out for a week, people who eat loudly or drivers who don’t park at the back of the box on a street with very limited parking (that last one might just be me). It’s an annoyance that lingers, festers and keeps you muttering to yourself. And maybe sneaking out in the middle of the night to leave a rude note on someone’s windscreen.
‘Rankle’s etymology is quite literal – it came into English from an Old French word, ‘draoncle’, which meant ‘boil’ or ‘festering sore’. Lovely. That comes from a Latin word, dracunculus, which is less gross – it means ‘little serpent’ or ‘little dragon’ (and would have been an ace name for one of the Game of Thrones dragons).
So how did we get from serpents to sores? Well, in the ancient world, apparently people thought some ulcers looked like wriggling little snakes under the skin. I’m not googling this to check though.
When ‘rankle’ first slithered into English in the 14th century as ‘ranclen’, it was all about wounds festering away. Then, over the next couple of centuries, writers started using it in the figurative sense for feelings that behave like sores that refuse to heal. Shakespeare was of course leading the pack, using it as a metaphor for an emotional condition in Richard II:
‘Fell sorrow’s tooth doth never rankle more
Than when he bites, but lanceth not the sore.’
Thanks to our Will, and others like him, when something rankles today, there’s no pus involved. And ‘no pus involved’ is always a good thing, right?
