When learning English pronunciation, many learners mix up the vowel sounds /ʌ/ and /ɑː/. Even though they look similar in spelling, they sound very different and can change the meaning of words. These pairs are called minimal pairs—words that only differ in this one vowel sound. Let’s learn how to tell them apart!
