▷ librar|ies iz —The awkwardness of two r s in the same unstressed syllable makes people tend to drop the first of them. While perhaps condemned by the speech-conscious, such reduced pronunciations are nevertheless often heard from educated speakers. Where in American English the second syllable has a strong vowel, the reduction is more noticeable, hence less frequently heard and more strongly disapproved of.
