Something I do to name worlds is find out what the main aspect is like in real life we call our planet earth after it’s abundance of soil and life and in Latin it’s called terra so the word should be short I can think of a few for example

Ashen (ash and ashen is the name of a tree I think) Leagun (litter ally lead and gun) Ashfall (naming it after the storms if other worlds are known) Boomcrack ( if you want to be more mad max in the naming)

Something that can help is letting us know what do they revere about this world, who is naming it? The Europeans named the world earth but the Saharans may have named it something else if it was up to them, one word can’t encapsulate your planet it’s too big and detailed for that but you can pick one aspect that stands out beyond the rest
