Estribillo:
Chorus:

Guantanamera, guajira** guantanamera

Yo soy un hombre sincero, de donde crece la palma
I am an honest man, from where the palm tree grows
Yo soy un hombre sincero, de donde crece la palma
Y antes de morir you quiero cantar mis versos del alma
And before dying I want to sing the verses from my soul.

Estribillo

Cultivo una rosa blanca, en julio como en enero,
I'll grow a white rose in July just like in January,
Para el amigo sincero, que me da su hano franca.
For the honest friend, who gives me his open hand.

Chorus (twice)

Mi verso es de un verde claro, y de un carmin encendido
My verse is [of] a light green, and [of] a burning scarlet
Mi verso es de un verde claro, y de un carmin encendido
Me verso es un clervo herido, que busca en el monte amparo.
My verse is a wounded stag, who seeks refuge on the mountain.

locura , noun:

madness, insanity

La locura, madness, is the noun derived from the adjective loco.

Huyen de la hambruna y la locura colectiva que asola sus países.
They’re fleeing the famine and collective madness devastating their countries.

Locura is used in a couple of very idiomatic phrases. First, es una locura, it’s crazy, it’s mad:

Es una locura pero tenía que venir.
I know it’s crazy, but I had to come.

And then in the phrase hacer locuras:

No hagas locuras.
Don’t do anything crazy or stupid.
