The common mispronunciation of “insure”
✗ Often said: /ˈɪnsjuːr/ — the spelling, read straight off the page.
✓ Actually: /ˌɪnˈʃʊr/
Why the two come apart: the silent final “e” (it lengthens the vowel instead) is not pronounced, even though the spelling begs you to say it; also, the stress lands on the second syllable (“ʃʊr”), not on the first one — putting the beat at the front is the mistake almost everyone makes.
This is why reading English aloud from spelling alone goes wrong so often: the letters of “insure” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
