liberate (v.) Look up liberate at Dictionary.com
"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.
