The Chozo Language is a runic language used by the Chozo. Though the language has never been spoken aloud in-game, there are many examples of the written Chozo language in their settlements, such as the ruins on Tallon IV. The language is so complex that Samus's Translator Module has at times had difficulty in translating it, and Space Pirate language databases and linguistic analysts have had even less success.
Much like the Luminoth, who use their written language as locks to block access to key areas, the Chozo also used Runic Symbols, likely a part of their written language, to hinder intruders. Chozo runes were also etched into the surfaces of the 12 Chozo Totems and could be scanned to gather clues concerning the Chozo Artifacts.
- "This runic symbol has been activated. Four runic symbols in this room must be activated." —Scan Data (Metroid Prime)
- "The only translatable symbol detected on this sculpture is the word 'Chozo.'" —Scan Data (Metroid Prime)
- "We have come to another dead end. It is clear now that we will never discover the locations of the Chozo's artifacts until we can decipher the messages carved into the statues in this abominable temple. Our language databases are woefully inadequate, and our linguistic analysts can come up with little more than vague theories. The best hypothesis we can offer is that finding the artifacts will require items spiritually linked to the Chozo civilization. However, without these items, we are lost, and Command grows more impatient by the day. Results must be produced soon." —Pirate Data "Artifacts" (Metroid Prime)
- "Translating Chozo runes on Totem's surface. The Artifact awaits those who truly seek it." —Scan Data (Metroid Prime)
