Here are some tips:
If you have created a fictional language, go ahead and create fictional words for these terms. Our terms might not be culturally appropriate anyway, depending on your world.
For example, a culture might have different words for someone who is a bisexual male and someone who is a bisexual female. Therefore, you could create two different words.
However, when it comes to creating fictional words, it’s good to be clear on what they mean. As an example, I’ll use the word “allromnilo” to mean “bisexual male” and “allromnelu” to mean “bisexual female”. Refer to bisexual males as “allromnilo” enough times and in the right context (when talking about relationships, who they are attracted to, etc.) to show the reader what this word means. Do the same thing for “allromnelu”.
You can take it further by switching the order to show preference. A bisexual woman with a preference for women would therefore be called “romallnelu”. A gender neutral option to our bisexual alternative could be “allromnol”.
Here are all the words so far:
- Allromnilo - bisexual male
- Allromnelu - bisexual female
- Allromnol - bisexual
- Romallnelu - bisexual female, preference for women
These words are all pretty similar, so if you do something like this is might be easier to create words that are not so similar or to create fewer words. You can put a dictionary in the back, but it’s still important to give context within the text alone.
It’s not bad to create words like this (especially since many cultures have different ways of describing stuff like this), but it’s so rare to find characters just outright say what they are in a situation that is not a big coming out moment.
It’s especially rare to find someone say they’re bisexual. There’s always some speech about how it “doesn’t matter what this person likes and blah blah blah let’s not put labels on it”, which erases bi/pan people and which also allows people to avoid talking about a subject that makes them somewhat uncomfortable.
So it’s not bad to use fictional words, but it’s good to use real words to break down the taboo that surrounds them.
BUT DO MODERN WORDS DISTRACT FROM MY WORLD?
Maybe. Maybe not. It really comes down to whether it feels “right” in your world or not and whether you could see your characters casually using these terms.
