usage While the pronunciation \ˈlī-ˌbrer-ē\ is the most frequent variant in the United States, the other variants are not uncommon. The contraction \ˈlī-brē\ and the dissimilated form \ˈlī-ˌber-ē\ result from the relative difficulty of repeating \r\ in the same syllable or successive syllables; our files contain citations for these variants from educated speakers, including college presidents and professors, as well as with somewhat greater frequency from less educated speakers.
