I am not to hot on those alternate spelling names. Takes me half an hour to decipher them, by then I will usually have lost interest.
You could do a small brainstorm on the subject of infinity and just jot down all the words YOU associate with infinity. Don’t judge, write down whatever pops up. When you think you are out of ideas, make yourself come up with at least three more words (often the best ones come out of those last three).
Then let it sit for a few days. If no name/word pops out at you, start deleting those that really are not relevant, appropriate or usable. Then you can do the a/b comparison method of selecting the best of the remaining words. Finally when you have a few final words that describe what infinity means to you, you can try merging that into one name.
Just a thought.
