What does the word " Dāsa " actually mean?

This word confuses me a lot Dāsa. Many people consider it to be translated to servant but when you look for verses in text like manusmriti, it is translated into as slave for example: https://preview.redd.it/wtf3hh87abce1.png?width=449&format=png&auto=webp&s=3ab20848247c6e9faa3e7cf730fb6bbf356b7eb3 In above verse the word "presyo" is translated as servant while the word dasa is translated into slave: https://preview.redd.it/fzl1vy9fabce1.png?width=421&format=png&auto=webp&s=b84b2c15c82ac51721fdd21c96d3f10a82bd6314 This is making me really confused, **does this mean slavery was allowed in hinduism?** dasa also get translated as devotee, enemy of arya according to wisdomlib dict. : https://preview.redd.it/pu5gmzlyabce1.png?width=210&format=png&auto=webp&s=d0c9be3e551ddcad51b4df157da650d3c1c2dbbc It's translation also varies with text, with shiv puran translating it to slave and in  Kubjikāmata-tantra it is translated as servant ( according to wisdomlib) why couldn't ancestors just come up with different words😭
