As a new science fiction / fantasy author one of the problems I am wrestling with is the degree to which I make up new words or terminology. If a species or culture is alien (not-Earth based) then how much do I differentiate the language and terminology that I use?
For example the period it takes for the Earth to orbit the Sun is called a year. A day is how long it takes for the Earth to rotate once. But would another species use the same words, or would they have other words to reflect the same meaning? The obvious answer would be that they would use different words… (unless they had a shared history with Earth).
However I want my readers to be able to understand what I am writing without having to interpret a new language. I want to immerse my reader in fictitious places, but I don’t want them to be incomprehensible. A delicate balance.
