Semper Fidelis
Always faithful, translated
Semper Fidelis is Latin for "always faithful," the motto of the United States Marine Corps since 1883.
Marines use it as a greeting, farewell, or expression of solidarity, often shortened to Semper Fi.
The phrase emphasizes loyalty to corps, country, and fellow Marines: Once a Marine, always a Marine—Semper Fi.
