Mandalorian served as the written form for Mando'a, which was the spoken language utilized by the Mandalorian people. It also functioned as a script for Galactic Basic reading and writing.
During the Clone Wars period, members of the Mandalorian secret service displayed a crest on their uniforms, specifically on the shoulder area, which bore the inscription "IN DEFENSE OF MANDALORE".
In the era of the Galactic Civil War, the Mandalorian Protector Fenn Rau was under attack on the third moon of Concord Dawn; as he departed in his Fang fighter, his cockpit monitor displayed "TARGET LOCKED" in the Mandalorian writing system. Later, when Kanan Jarrus infiltrated Rau's fighter, the monitor's message changed to "WARNING".
Subsequently, Mandalorian script was found etched onto a wall within Maul's sanctuary, located in the Nightsister lair on Dathomir. The inscription read "KENOBI," reflecting Maul's intense fixation.
Sometime after the Galactic Empire's downfall, a holographic representation of Boba Fett's chain code was presented in Mandalorian, arranged vertically from top to bottom. This code included segments such as "FOUNDLING," "TOOK INTO", "THE YEAR THE", "CONCORD DAWN," "MENTOR JASTE," "FATHER FETT," and "BOBA FETT."
Subsequently, the Mandalorian Din Djarin presented The Armorer with a segment of Mandalorian inscription on a green trinitite fragment. He had obtained this fragment from Jawas, who in turn had acquired it from an individual who had visited Mandalore, a planet devastated during the Great Purge. The inscription, displayed in a mirror-inverted manner, read:
A video monitor viewed by R5-D4 inside Din Djarin's N-1 starfighter showed:
This same text was displayed on a monitor within the console of Bo-Katan Kryze's Gauntlet starfighter.
A commemorative plaque near the mystical waters inside the Mines of Mandalore stated:
Interestingly, when Bo-Katan Kryze read the plaque aloud to Djarin, she reinterpreted "Mandalore the Great defeated and rode the mythical beast" to mean "Mandalore the Great is said to have tamed the mythical beast."
During a combat training session involving two young members of The Tribe at the covert's beach, two boxes were observed in the sand nearby, each marked with Mandalorian labels. One box was labeled "FOU: G," while the other was labeled "FOU: J." A similar box was located in a cave when Djarin addressed the rest of The Tribe, and it was labeled "TRO:G."
As Kryze piloted a flight over Plazir-15, the phrases "LAND: VECTOR" and "NAV" appeared on two monitors within the console of her Gauntlet starfighter. After the planet's automated system took control of the ship, the phrase "CONTROL OVERRIDE" flashed on a different monitor. Later, when Kryze flew over Nevarro, three Mandalorian words were displayed on the first two monitors, with the third word being "NAV," mirroring the display seen over Plazir-15.
Two Mandalorian flags were placed in the camp of a Mandalorian privateers group on Plazir-15.
After the covert gathered at their destination on Nevarro, one of the boxes they transported was labeled "1024".
In the period leading up to the First Order-Resistance War, the logo for a business specializing in snow cones was written using the Mandalorian script, spelling out "SNOKE CONES".
The segment of Mandalorian inscription that Din Djarin presents to The Armorer in The Mandalorian episode "Chapter 17: The Apostate" originates from verse 10:5-6 of the Book of Exodus within the King James Version of the Bible. Verses 10:5-6 describe the plague of locusts, one of the ten Plagues of Egypt, drawing a parallel to the Purge of Mandalore. The complete verse is as follows (the text displayed on-screen is in bold):
