Another endemic confoozlement that drives me crazy(er) is the misuse of:

"Stanch" and "Staunch".

"Stanch" is a verb, to stop the flow of a liquid (especially blood).

"Staunch" is an adjective: Steady in principle, loyalty, adherence. etc. As in a staunch friend, a staunch patriot, a staunch Republican.

As, "When I was wounded, my staunch friend Joe rushed to stanch the bleeding."
