According to online dictionaries, the Hindi word बर्बरता (barbarta) means barbarism, savagery, brutality or cruelty. It describes behaviour or an act that is extremely violent, ruthless or uncivilised, often used for atrocities, inhumane treatment or acts of extreme cruelty.
For example, “इस हमले में जो बर्बरता दिखाई गई” would translate to “the barbarity shown in this attack.”
It shares its root sense with the English word barbarity, both ultimately tracing back to the idea of something outside civilised, humane conduct.
