Over explaining ruins my suspension of disbelieve more than any convenient similarities. Whatever rules you set, stick to them right from the start. Don't overthink language unless you're willing to go the whole mile in feeling out all of the differences.

I disagree with the idea of having made-up words here and there just because scifi. If you're going to base it in real language, then make your "made-up" words make sense in those languages, too. People don't name things well or artistically. They name things for practicality and understanding. So if you need a word for something that doesn't actually exist and you're already using real world terms for everything else, keep it simple.
