Every time I see someone use the term ‘Jedis,’ I sigh.

Maybe it’s petty, but few things drive me battier than glaring Star Wars typos, particularly when they come from professional and semi-professional news outlets. Here are a few Star Wars terms and spellings every fan (and entertainment journalist) ought to know and use correctly in the years ahead.

Lucaswhat?

Lucasfilm, or Lucasfilm Ltd., is the parent company that makes Star Wars, Indiana Jones, and other films. LucasArts is their gaming division. LucasArts does not make movies – they make and oversee games. Other divisions of Lucasfilm: Industrial Light & Magic (special effects,) Lucasfilm Animation, Lucas Licensing and Skywalker Sound.

And no, it’s not LucasFilm, Lucasfilms, LucasFilms or Lucas Films. Lucasfilm.

How many Jedi?

The plural of Jedi is Jedi. The term is both singular and plural, like ‘fish.’ Sith is the same way.

Extended or Expanded?

They may indeed extend the Star Wars galaxy, but the official umbrella term for Star Wars books and comics is Expanded Universe.

Know your hyphens

There’s no hyphen in Jar Jar, but there is one in Obi-Wan, Qui-Gon, X-wing, R2-D2, and C-3PO. (The phonetic spellings of Artoo and Threepio are perfectly acceptable, though.)

Other things that are frequently misspelled/punctuated:

The Force is capitalized. (And it’s the Force , but the the isn’t capitalized, generally.) The dark side is not capitalized. At least for the moment.

is capitalized. (And it’s , but the the isn’t capitalized, generally.) The is not capitalized. At least for the moment. Anakin has two a’s and only one i.

has two a’s and only one i. There are two e’s in Wookiee . And when referring to the mighty Chewbacca by his nickname, it’s spelled Chewie , not Chewy.

. And when referring to the mighty by his nickname, it’s spelled , not Chewy. There are no u’s in Padawan .

, not Rouge Squadron. (Unless you’re a Club Jader deploying Attack Pattern Clinique, that is.) Ahsoka is the character on The Clone Wars . Ashoka was an Indian emperor who reigned 269 to 232 BCE.

is the character on . Ashoka was an Indian emperor who reigned 269 to 232 BCE. It’s a TIE Fighter , not a Tie Fighter. TIE stands for Twin Ion Engines. In the same vein, there’s AT-AT (All Terrain Armored Transport) and AT-ST (All Terrain Scout Transport.) There will not be a test, so just remember the capitalization. (h/t @JalenJade)

are , not taun tauns or ton tons. It’s okay if you have to Google Kashyyyk . I mean, look at that thing. (Pretty much any Star Wars planet can – and probably should – be Googled to make sure it’s correct, and praise Wookieepedia for having such a high ranking.)

. I mean, look at that thing. (Pretty much any Star Wars planet can – and probably should – be Googled to make sure it’s correct, and praise Wookieepedia for having such a high ranking.) I won’t ding you for this one (and I don’t even do it myself most of the time,) but do note the accent mark in Padmé.

Obviously this isn’t everything – how on Earth people manage to misspell Zahn is beyond me – but they are the most glaring. What typos drive you batty?
