Slave-girl
From wipipedia.org
Slave-girl is the closest English has to a feminine form of the word slave. Since 'slave-girl' can be applied to women who are no longer literally girls, it is part of the language's wider habit of using the words girl and boy to indicate lower status.
A slave-girl may be the inhabitant of a harem rather than a woman used as a labourer.
Kajira is an invented equivalent word, used in John Norman's Gor books.
