Usage Note: Traditionally, the first syllable of Zoology has been pronounced as (zō), rhyming with toe. However, most likely due to the familiarity of the word zoo (which is merely a shortened form of zoological garden), the pronunciation of the first syllable as (z) is also commonly heard. In 1999, 88 percent of the Panelists found the (zō-) pronunciation acceptable, and 60 percent found the (z-) pronunciation acceptable, with 68 percent using the (zō-) pronunciation and 32 percent using the (z-) pronunciation in their own speech. Thus, while both pronunciations can be considered acceptable, the (zō-) pronunciation may be perceived as more scientific.
