A Fantasy Author's Search History: What is a knight?

What is a knight? Well, put very simply, a knight is a specific type of mounted medieval fighter. They begin as squires when they are young and train until they achieve their own knighthood. They could even have their own castles and staff.

This was an oops moment for me. I mistakenly assumed that knights was a general name for medieval soldiers, but it's not. I found this out over a year after writing Reawakened Flames when I read "Writing Fantasy & Science Fiction" (Card, Athans, Lake) and after getting into a YouTube channel called Modern History TV.

I hadn’t been sure what to call the fighters in my book and wanted a name that I could use consistently. Otherwise, I was going back and forth between soldiers and warriors. Now, my books are not historical fiction, so I guess my broad usage of "knight" is fine.
