Yes, Dick has been a nickname for Richard for about 800 years but only got its modern slang meaning in probably late-19th or early 20th century. It seems to have come out of the British military from the phrase "Tom, Dick, and Harry", which were such common names that the phrase meant every ordinary man. (Tommy was already slang for "British soldier".) And from there, one more evolutionary step for mankind....

The English form of daughter was also -dottir, but it was not common.

Would a bit of Post-It Note (for minimal adhesion) damage the screen coating if left on most of the time? Would even that much thickness stress the screen when opened and closed thousands of times? Is there a better (self-service) material?

It's a little sad, but you're right of course that many books no longer make business sense now that everything they offer is online and free. Well, when the AIs put us all out of business and we're home all day in our rabbit hutches, we'll have plenty of time and free content to read.

Ah, I thought your name sounded familiar! In 2008, I bought "Reading Japanese with a Smile" on a trip to Japan and loved it. It was very well done and perfect for me. I ended up buying two copies and for years I kept checking on Kinokuniya visits hoping it would become a series. No such luck, but my guess is it was just too much work for too little reward. But you should know that a HN reader still remembers your work fondly after 16 years.
