More about liberation
Liberation “the act of gaining equal rights” is adapted from Latin līberātiō “a setting free, a release,” which comes from the verb līberāre “to free” and, ultimately, the adjective līber “free, open, frank.” From here, there is the possibility for confusion, as the adjective līber “free,” the noun līber “child,” and the noun liber “book, bark” are all common words in Latin. Līber “free” is also the source of deliver, liberal, libertarian, and liberty, and it comes from an ancient root meaning “people”; compare the names Leopold (literally “bold people”) and Luther (“people army”). Līber “child” literally means “free one” and almost exclusively appears as plural līberī “children.” Meanwhile, liber “book” is the source of libel, library, and libretto, and it is unrelated to either līber. Take care not to confuse these nearly identical words! Liberation was first recorded in English in the early 15th century.
