Did You Know?
The verb "stanch" has a lot in common with the adjective staunch, meaning "steadfast." Not only do both words derive from the Anglo-French word estancher (which has the same meaning as "stanch"), but the spelling "s-t-a-n-c-h" is sometimes used for the adjective, and the spelling "s-t-a-u-n-c-h" is sometimes used for the verb. Although both spelling variants have been in reputable use for centuries and both are perfectly standard for either the verb or adjective, "stanch" is the form used most often for the verb and "staunch" is the most common variant for the adjective.
So there are one of two truths here. Either the author is HIGHLY sophisticated regarding his understanding of the USE of the word(s) OR he is highly unsophisticated. haha. A small but poignant detail regarding these two words and their usages.
I think the author just made an error. I have seen that error on many occasions and have almost made it myself.
