High Galactic alphabet The High Galactic alphabet was a form of writing in the galaxy . While not as common as Aurebesh , this alphabet was frequently used in signatures and by nobles , and was often associated with snobbery . It was most commonly used to write Galactic Basic Standard . High Galactic letters came in two forms : a printscript , in which all letters were separate glyphs ; and a handwritten , cursive form , in which the strokes of successive characters were joined and the angles rounded . While the High Galactic alphabet normally distinguished between the letters that were in larger uppercase and smaller lowercase , many logos were written entirely in capital letters . Origins and history . The alphabet originated as part of the High Galactic language , which was spoken by the colonists of Alsakan prior to 17 , 000 BBY , and originated during the war between the Galactic Republic and the Tion Cluster . The alphabet entered widespread galactic use in approximately 17 , 000 BBY , during the Alsakan Conflicts . The Alsakanese borrowed characters from Tionese language and introduced others of their own invention , creating a writing system with no ties to the Aurebesh or related scripts . Millennia later , the alphabet continued to see fairly widespread use . By circa 22 BBY , Republic Census figures showed that the High Galactic alphabet was used by nearly one third of Galactic Basic speakers when writing , and by over half of upper - class Basic speakers . As a result , Aurebesh and the High Galactic alphabet were often presented side by side . Nearly all Basic advertising was presented in the High Galactic alphabet , as were corporate logos that incorporated written language , such as those of Industrial Automaton , the Corellian Engineering Corporation , and Sienar Fleet Systems . The High Galactic alphabet was also used for naming many starship models ( such as the T - 65 X - wing starfighter ) and droid models ( such as the R2 series of astromech droids ) . Texts written in this alphabet . Although this alphabet was less common than Aurebesh , there is indication that whole ( although few ) texts were written in it . Following are several examples : Signatures . Many Humans — and some non - Humans — used this alphabet in their signatures , instead of the more common Aurebesh , perhaps by tradition . Those individuals included : Droid names examples . Droid names often derived from letters in this alphabet : Behind the scenes .

This article describes the occurrences of the English alphabet in the " Star Wars " universe . Although canon and Legends have both established the fictitious writing system of Aurebesh , it is somewhat unsurprising that this alphabet , especially its variant , appears in the " Star Wars " universe , as the " Star Wars " movies and most Expanded Universe materials are of American origin . Canonicity . The Latin alphabet has appeared in several instances of the original trilogy and the Expanded Universe , but its appearance was unexplained before it was dubbed the " High Galactic alphabet " in the - exclusive article " The Written Word " . Roman labels in were edited into Aurebesh in the 2004 DVD release , suggesting that George Lucas believed that real - world Roman letters don ' t belong in the " Star Wars " universe .

" Some instances show both Roman and Aurebesh alongside each other ( such as the Corporate Sector Authority logo ) , showing that the two coexisted . Various starfighters ( X - wing , Y - wing , A - wing , etc . ) were named for characters from the Roman alphabet , as the shapes of these craft do not match the shapes of the corresponding letters in Aurebesh . Other craft were named after letters in the Aurebesh alphabet ( " Aurek " - class tactical strikefighter ) or real - world ( " Lambda " - class T - 4a shuttle ) . Droids , too , are named with the alphabet , such as R2 - D2 being called " Artoo - Detoo " rather than " Reshtoo Dorntoo , " and C - 3PO being See - Threepio and not Cresh - ThreePethOsk .
