This is a language pet peeve that bothers me a lot when I see it. It’s when people use “whence” incorrectly.
How do we use the word “whence” properly?

Whence means “from where,” yet when I see people using it, they often say “from whence they came.” This drives me crazy. What you are really saying is “from from where they came.”

Correct usage:
“…the old village whence they came.”

Whence is an archaic word, so if you must use it, please do so correctly and leave off the unneeded “from.”
