Pronunciation

Library, with one r -sound following close upon another, is particularly vulnerable to the process of dissimilation—the tendency for neighboring like sounds to become unlike, or for one of them to disappear altogether. The pronunciation , therefore, while still the most common, is frequently reduced by educated speakers, both in the U.S. and in England, to the dissimilated or . A third dissimilated form is more likely to be heard from less educated or very young speakers, and is often criticized. See colonel, February, governor.

Etymology

Origin of library

First recorded in 1300–50; Middle English libraire, from Middle French librairie, from Medieval Latin librāria, noun use of feminine of Latin librārius (adjective) “of books,” from libr-, stem of liber “book” + -ārius -ary

Explanation

A library is a place where collections of books are kept. If you ever want a reminder of how very much there is to learn in this world, pay a visit to your local library. The noun library, meaning, “a room or building where books are housed,” comes from the Latin librarium “chest for books.” That, in turn, evolved from the Latin liber, a word meaning “book, paper, parchment,” and, more literally, “the inner bark of trees.” The writer Jorge Luis Borges said, “I have always imagined that Paradise will be a kind of library.” What would your vision of paradise look like?
