Yeah, well . . . . . . . . .
As far as rex is concerned we meet the word on a daily basis.
As a monarchy, our coins have around the edge:
Monarch D G REX or REG F D as in
George VI DEI GRATIA (by the will of God) Rex (King) Fidei defensor (Defender of the Faith).
So rex or regina jingles around in our pockets. Might even be in your pocket if you have any very old coins.
The name Rex means King from the Latin. Rex is a common boys' name. Rex Harrison, actor. Rex Reed, journalist and thousands more.
Then you have the well known classic
Oedipus Rex, also known by its Greek title,
Oedipus Tyrannus (Ancient Greek: Οἰδίπους Τύραννος, pronounced [oidípoːs týrannos]), or
Oedipus the King, so Tyrannosaurus Rex means King king, and so it goes on . . . and on . . . and on . . .
Good old Rex just keep popping up all over the place.
Try thinking "rex" every time the coins jingle in your pocket.
Good Luck and Best Wishes, and I hope you have many jingling coins to remember our Rex by.
