Etymology
Origin of zoology
Explanation
If you're fascinated by monkey business or just love horsing around, you might consider a career in zoology — the scientific study of animals. According to some usage experts, most of us mispronounce the word zoology. The first syllable of this noun is correctly pronounced with a long o sound, as in toe, rather than the "oo" in zoo. Yet our error is considered acceptable because if you're going to study animal life and behavior, one of the best places to do it is at the zoo.
