What is Semper Fidelis?
"Always Faithful" — the Marine Corps motto, used as a greeting, affirmation, and rallying cry.
Definition
Semper Fidelis — shortened to Semper Fi — is the Marine Corps motto, meaning 'always faithful.' It functions as a greeting between Marines, an expression of Corps pride, and a statement of commitment that extends beyond active service. Marines say Semper Fi to each other at funerals and reunions, at chance encounters in airports, and at difficult moments when the commitment of service needs reaffirmation.
In Dating & Relationships
Semper Fi is a promise that never expires — and for Marines in relationships, 'always faithful' is not just a motto but a lived commitment that shapes everything about how they love.
