So why did I choose the name Plexis for one of my character's nickname? I had Usse - which was a wink at the Greek's fondness for names ending in "us" - and I used some of the French spellings for some of the names (this is fiction - a time travel book - so I took a few liberties...) Anyhow. Plexis. Why? Well, I liked the sound of the name. Hephaestion is stuffy, and the Greeks had nicknames, just like anyone else, so why not Plexis?
The word Plexis comes from the Proto-Indo-European "pleḱ"- (“to fold, weave”). It's associated with the Latin plicō, Ancient Greek πλέκω (plékō). I thought the folds and weave of a cloth would suit Plexis's character - he comforts Ashley, he's Alexander's best friend, he is quixotic, but at the same time he has a practical side to him. He's a complex character, with many layers to his personality.
And there you have it. A name, just a name, and a reviewer crucifies the story. Maybe the name wasn't at all what the reader hated - but the whole review, just one sentence - only mentioned the word Plexis as if it were the worst thing the reader had ever come across, so I felt I had to explain in case someone else reads the book and wonders where I found the name - now you know, Plexis is a name I made up from an ancient word that means the fold or weave of cloth. It's nothing too deep, just a sound I happened to like with a meaning that spoke to me.
