Well, Sindhu is, I believe.
The Sindhu River, now the Indus.
The invading Muslims called those who lived around and beyond the Sindhu River “Hindus” since they often subsituted “H” for “S”. Nowhere in the Vedas can the word “Hindu” be found. The system of culture and religion taught in the Vedas is usually called sanatan dharma, or varnashram dharma. Among other words. The word “Hindu” has only been used since the time of the Muslim invasions.
