The /ʌ/ sound, on the other hand, is a lazy, relaxed grunt-like sound produced in the center of the mouth with the mouth only partially open. I call it the caveman sound because I believe it could be the first sound man ever made. It will also likely be the last. By the way, it's basically the same as the English schwa sound /ə/, the difference being that /ʌ/ is stressed and /ə/ is unstressed.
Below is a list of words with these sounds. Some of these are near minimal pairs as they differ in more than one way. But most are true minimal pairs. The last one with "z" is the first syllable of some guy's last name.
