Language of The Ancients

Ancient language or Alteran language are the names given to the language spoken and written by the Alterans that consist of two factions: The Ancients/The Ancestors/Lanteans and the Ori. The language was given to Earth humans in the past where it eventually evolved into Latin. Both languages are little similar to each other.
The alphabet and numeral system used by the Alterans have interesting and special appearances: the symbols consist of squarish dots, and as a "full symbol" there are 24 squares with 8 on each diagonal row, except the letter k. Just like the Latin alphabet in English, the Alteran alphabet has all of its letters, while both f and u have the same symbol. Classical Latin did not have j and w, but came later and can be used for names.
In Atlantis, the letters and numbers of the Alteran alphabet appear both upright and upside down and variate in direction. This is likely an error in production - telling the correct way up is difficult if you don't know the language.
Speakers Several people at Stargate Command were successful in understanding written and spoken Alteran. Dr. Daniel Jackson was the one who unlocked the mysteries of the language, so that more could learn it, and gained an innate understanding after his Ascension and subsequent decension. Other people who are fluent in the language or at least understand it at a reasonable level are Jonas Quinn, Dr. Rodney McKay, Dr. Elizabeth Weir, Colonel Samantha Carter, Colonel Harold Maybourne, Dr. Nicholas Rush, Eli Wallace, Dr. Adam Brody, Dr. Dale Volker, Dr. Lisa Park, Dr. Amanda Perry, Dr. Lindsay and several others.
