The spelling of the word "tibiaeus" may seem confusing, but it follows the phonetic rules of English. When pronounced, the word is actually "tɪˈbiːiəs," with a stress on the second syllable. The "i" in the first syllable is pronounced like a short "i" sound, and the second "i" in the second syllable is pronounced like a long "e." The suffix "-eus" is added to "tibia," which refers to the shinbone in biology. Despite its complex spelling, "tibiaeus" can be easy to pronounce with a little practice!
