A lot of Latin roots reveal such misinformed associations, as well
Lunatic - (perhaps akin to sundown syndrome) that one’s ability to stay rational was compromised by the presence of the moon
Hysteria - that out of control emotional behavior was a result of a malfunctioning uterus (maybe this association isn’t so misinformed...).
You do realize that all left-handed people are sinister, right? (Latin for left!)
One that I am uncertain about is the phrase "Takin' it for a spin!", which now days refers to automotive actions. I don't know where this came from in my memory, but I seem to think that this once referred to phonograph record stores where they had booths to listen to a record before buying - thus "Takin' it for a spin!" (Real old time here!)
Of course, going back to Latin roots, the word "record" comes to English from French and was derived from the Latin "recordari", to remember.
