"set free, release from restraint or bondage," 1620s, from Latin liberatus, past participle of liberare "to set free" (source also of Spanish librar, French livrer), from liber "free, not a slave, unrestricted" (see liberal (adj.)). Meaning "to free an occupied territory from the enemy" (often used ironically) is from 1942; hence the World War II slang sense "to loot." Related: Liberated; liberating.
