The common mispronunciation of “cooperate”
✗ Often said: /ˈkuːpəreɪt/ — the spelling, read straight off the page.
✓ Actually: /koʊˈɑːpərˌeɪt/
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 (“ɑː”), not on the first one — putting the beat at the front is the mistake almost everyone makes; also, at least one vowel does not say what its spelling suggests — English vowel letters are not reliable here.
This is why reading English aloud from spelling alone goes wrong so often: the letters of “cooperate” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
