enslaved person / slave

Slave and enslaved person both name a person held in slavery. Slave is the long-standing word in history and law. Enslaved person (and enslaved people) is person-first wording: it puts the person first and treats slavery as a condition imposed on them. It is not a euphemism for slave, and it is not merely a more formal synonym. Use either form for people. Keep slave in fixed compounds such as slave trade, slaveholder, and slave labor. Do not rewrite those compounds with enslaved.
