The Sanskrit word ā́rya (आर्य) was originally a cultural term designating those who spoke Vedic Sanskrit and adhered to Vedic cultural norms (including religious rituals and poetry), in contrast to an outsider, or an-ā́rya ('non-Arya').By the time of the Buddha (5th–4th century BCE), it took the meaning of 'noble'.
