gantlet

“Gantlet” and “gauntlet” are two different words that people confuse for the same word spelled differently. “gauntlet” means glove, so you throw down the gauntlet, and “gantlet” means ordeal, so you run the gantlet. The problem is, most people say “run the gauntlet,” so usage enforcers, such as copy editors, have to keep reminding people they are wrong.

A gantlet refers to moving while under attack from both sides, as in to run the gantlet. A gauntlet is a glove. To throw down the gauntlet means to issue a challenge.
