IPA: /ˈfriːd.mən/
KK: /ˈfridˌmæn/
A man who has been released from slavery and is no longer a slave.
After the Civil War, many freedmen sought to build new lives for themselves and their families.
Freedman is formed from "free" (from Old English "freo", meaning not in bondage or liberated) and "man" (from Old English "mann", meaning a human being or person). The term refers to a man who has been liberated from slavery or servitude.
Think of a 'free' person who is no longer in bondage — that's what a freedman is.
