ˌmælˈɛvələnt
Here's a breakdown:
* ˌmæl: The first syllable is stressed, with a "mal" sound similar to "mall."
* ˈɛv: The second syllable is unstressed, with a short "e" sound like "eve."
* ə: The third syllable is unstressed, with a schwa sound, like the "a" in "about."
* lɛnt: The final syllable is unstressed, with a long "e" sound like "lent."
So, it is pronounced with a stress on the first syllable, and a relatively short sound on the rest of the word.
