According to Asko Parpola, the term dasa in ancient Indian texts has proto-Saka roots, where dasa or daha simply means "man". Both "dasa" and "dasyu" are uncommon in Indo-Iranian languages (including Sanskrit and Pali), and these words may be a legacy of the PIE root "*dens-", and the word "saka" may have evolved from "dasa", states Parpola. According to Micheline Ishay – a professor of human rights studies and sociology, the term "dasa" can be "translated as slave". The institution represented unfree labor with fewer rights, but "the supposed slavery in [ancient] India was of mild character and limited extent" like Babylonian and Hebrew slavery, in contrast to the Hellenic world. The "unfree labor" could be of two types in ancient India: the underadsatva and the ahitaka, states Ishay. A person in distress could pledge themselves for work leading to underadsatava, while under ahitaka a person's "unfree labor" was pledged or mortgaged against a debt or ransom when captured during a war. These forms of slavery limited the duration of "unfree labor" and such a slave had rights to their property and could pass their property to their kin, states Ishay.
