Just like naming your characters, naming your world and the places inside it can be difficult. You should give it some thought, but you might be able to just write down whatever comes into your head first.
1. Have names your readers will remember
Everyone knows Hogwarts. We all know Mt. Doom. They’re not fancy names. Hogwarts is out of this world while the word “Doom” is simple and common. Names don’t have to be simple but they should be memorable.
2. Avoid names that can’t be pronounced easily
Short names are good, long names are fun, a mixture of the two is great. However, when it comes to any name, you should be able to pronounce it easily. Even if your readers have to stop to sound it out, they should be able to make some sort of sense of it.
3. Take names from the things around you
Pay attention to the current world we live in. Graffiti is on the walls, names are in the credits of movies, you can easily take common names and turn it into something else. Some names you can probably use in your world as is. Not everything needs to be made up.
4. Play around with places that already exist
Scramble the letters in your hometown’s name. Spell it backward. Spell it backward and then scramble the letters around. The possibilities are endless.
5. Let names come to you
You don’t always have to sit and brainstorm name ideas. If your characters are going to a new town, you don’t have to know that town’s name right away. Refer to it as “Town A” and bold it so you can easily see it stick out when you’re editing later on. You can always think of a name later. A name may come to you when you least expect it.
