Martirio literally translates to "martyrdom", but is used here to mean immense "torment" or "agony". It's a powerful, dramatic word that you won't hear every day.
In this classic folk song, the singer says, "El que no sabe de amores... No sabe lo que es martirio" (He who doesn't know of love... doesn't know what torment is). This line beautifully captures the song's deep sorrow by equating the pain of love and loss with the suffering of a martyr.
This song is a classic for a reason! It's built around the legend of "La Llorona," the weeping woman from Mexican folklore, but here the singer uses her name to talk to a lover. The mood is set in a cemetery, where even the flowers seem to cry in the wind: "Parece que están llorando" (It seems like they are crying). The singer's pain is so huge that when they tell their sorrows to an iron statue of Christ, "el Santo Cristo lloró" (the Holy Christ cried). That's a pretty intense way to say you're heartbroken.
But it's not all sadness. The song is also a powerful declaration of love and identity. The singer promises they will never forget their lover, saying "Me quitarán de quererte llorona / Pero de olvidarte nunca" (They can stop me from loving you, Llorona / But from forgetting you, never). There's even a bit of a cheeky boast when they compare themselves to a chili pepper: "Yo soy como el chile verde llorona / Picante pero sabroso" (I am like the green chili, Llorona / Spicy but tasty). The song ends with a desperate plea, asking what more they can possibly give after having already given their life to this love.
