Slavery was a practice and institution where sentient beings were bought, sold, and held as property of other sentient beings. Beings subject to slavery were called slaves and said to be enslaved. Slaves were forced to perform labor on behalf of their owners, also called masters.
Indentured servitude was a nominally distinct practice in which sentient individuals performed labor for a fixed time period or until a specific amount of debt was paid off; after which point, they would be freed. However, in practice, indentured servitude typically amounted to slavery. Beings working in indentured servitude were called indentured servants, though that term was often a euphemism for “slave.” Another euphemism for “slave” was the term “sentient property,” which the Czerka Corporation used in official documents to grant a veneer of legitimacy to their practice of slavery.
Individuals who engaged in practices related to slavery, such as capturing people to make them into slaves, were known as slavers.
