The common mispronunciation of “ophthalmology”
✗ Often said: /ˈɑːfθælmɑːlɑːɡiː/ — the spelling, read straight off the page.
✓ Actually: /ˌɑːpθəˈmɑːlədʒiː/
Why the two come apart: the silent “l” is not pronounced, even though the spelling begs you to say it; also, the stress lands on the third syllable (“mɑː”), not on the first one — putting the beat at the front is the mistake almost everyone makes; also, the unstressed vowels flatten all the way down to /ə/ — English swallows them, so they never sound the way they are written.
This is why reading English aloud from spelling alone goes wrong so often: the letters of “ophthalmology” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
