how to pronounce library

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 [lahy-brer-ee], /ˈlaɪ brɛr i/, therefore, while still the most common, is frequently reduced by educated speakers, both in the U.S. and in England, to the dissimilated [lahy-buh-ree] /ˈlaɪ bə ri/ or [lahy-bree]. /ˈlaɪ bri/. A third dissimilated form [lahy-ber-ee] /ˈlaɪ bɛr i/ is more likely to be heard from less educated or very young speakers, and is often criticized. See colonel, February, governor.
