Hello,
At a dinner party on Sat, I insisted that it was grasp the mettle, and that grasp the nettle was an incorrect corruption of the original, but when I googled it this am, all sources seemed to say "grasp the nettle" with a couple of references to grasp the mettle as an alternative. Am I going mad? Or did I just learn the wrong one and it's stuck?..... I mean, it's not a phrase that you use every day, but I can't believe I got it wrong. The most arrogant part of me just thinks that everyone on the internet is wrong!
My pendant status has taken a bashing.. can any fellow pedants offer knowledge/support?
