Wondered how well this would work or if anyone would be put off by it. To put a long story short, the creatures I have created were forcibly made sentient by humans, who then partially-taught them English before the creatures escaped the space station they were being held captive in and started their own society on the planet they were orbiting.
The creatures are called Sindryl and mostly speak in English (as it is the only language they've ever known). However, for alien items not known to humans, words which they were never taught before they escaped, and newly-created items, they tend to make up words. As the world is inspired by Middle-eastern architecture and influences, I decided to make these made-up words more foreign-sounding. Things like 'fakisas' (sound a lot like fajitas), which are a sort of dessert food there, the use of the phrase 'tche tche tche!' (Pronounced 'ch-eh') when a Sindryl is in pain, and 'Isaiyo', meaning 'gangs'.
I have more words to add to this, but the whole point is: is this an understandable language behavior (to make up words when no word is available), and is it offensive in any way to other languages? I wouldn't think it is but I thought I'd check just to be sure.
Many thanks! - Rin
