And on top of that, explain why it is that capoeira terms are mostly spoken/written in Portuguese language. Capoeira [kapo-way-ra] is a martial art originated from Brazil, sometime near the beginning of 16th century.

Brief History In Brazil, generations of enslaved African people shared the cultural customs, dances, rituals, and fighting techniques that would combine to become capoeira. Slaves used capoeira to fight to escape and resist capture, but concealed its combative purpose through music, song, and dance.

Capoeira is best described not as a dance but as a sport in which the participants—historically, sometimes with blades strapped to their ankles or held between their toes—swing their legs high in attack, perform aerial somersaults, and pass within a hairsbreadth of each other's knees, head, groin, or stomach.

The most common way for someone to win in Capoeira, is to dominate the space in the roda, stifling the opponents movement.
