The common mispronunciation of “supervise”
✗ Often said: /ˈsʌpərvaɪs/ — the spelling, read straight off the page.
✓ Actually: /ˈsuːpərˌvaɪz/
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, at least one vowel does not say what its spelling suggests — English vowel letters are not reliable here.
