I was listening to an audio western book last night. I heard something that I have been hearing more commonly lately. "Chaps" as in chapped lips. The leggings we cowhands wear are not like the lips. The word comes from the vaqueros Spanish word "chaparejos". It is pronounced "shaps".
Second error was a cowboy raking his spur rowels across another cowboys leg and cutting 3/4" deep. This would not happen on bare skin much less through his jeans and maybe his boot tops too. Spur rowels are blunt.
Research is imperative. I know we all make mistakes despite our research efforts anyway. I am just hoping to help the dude authors and narrators get it right.
