The SW EU material, on the whole, isn’t exactly written by the most imaginitive authour in science fiction.
Wrong thread.
Are you implying that Robot Chicken is canonical Star Wars? Because I can get behind that.
I think that even a language which doesn’t have a letter X would probably still have some name for that shape. It’s a pretty basic shape that sees a lot of use.
Now, B-wing, for that I’ve got nothing.
Nor do I understand why they changed the written language on-screen, when they’re leaving the spoken dialog in English. Obviously they’re translating spoken Basic into English for the convenience of audiences-- Why can’t they be doing the same thing for writing?
Just how long ago does the Star Wars story take place? And in what galaxy, how far away?
Here’s my take:
The story occurs right here in the Milky Way Galaxy, at a time in the distant future when all that space-travel technology exists. But the story is being told by a narrator at some time even more distant in the future, and from a far-away galaxy. Thus, “A long time ago, in a galaxy far far away” really refers to our own futuristic galaxy. And one of the planets was Earth, although not mentioned in the story. But Earth people had populated the galaxy. This also explains the several Earthly-sounding names (Calrissian? Akbar? Falcon?)
Luke? Owen? Ben? 
Here’s the tweet I was thinking of…
He says (now at least) what you’re hearing is “There she…” as in “There she is.” Granted, it’s just his word, but I don’t know that any of us could hear There she vs. Carrie in that format OR that a (reasonably) professional actor would accidentally shout an actress’s real name in the middle of filming… esp. when the line was NOT for him to shout Leia there.
