In re "mun-ar", maybe you meant "monthly".

Etymology of "lunar": Middle English, from Latin lunaris, from luna moon; akin to Latin lucēre to shine [0]

Etymology of "moon": Middle English mone, from Old English mōna; akin to Old High German māno moon, Latin mensis month, Greek mēn month, mēnē moon [1]

You the Anglophones have this tendency to forget about the noble origins of your languages, just to reinvent it badly ;-)

In Kerbal Space Program, the moon is named Mun as opposed to our Luna: lunar -> munar

Edit: thanks to commenters for the reference to KSP. I had to ask Wikipedia what it is, and the first sentence is: "Kerbal Space Program (KSP) is a space flight simulation video game developed by Mexican studio Squad".

Mexicans forgetting about Latin is even worse than native English speaker doing the same!

It wasn't a mistake. KSP takes place in a solar system that is similar, but not identical to our own, and the planet the the space center is on, Kerbin, has a moon, called Mun.

They didn't forget anything. Try playing it for 10 minutes, it's fun :)

By mun-ar they were just referring to the Moon equivalent in KSP being called the Mun.
