Cap or Cup? How to see and say the difference between \/æ\/ and \/ʌ\/

Sometimes, the difference between crucial sounds in English can be very small. That is the case with 'cap' and 'cup', because the vowels /æ/ and /ʌ/ are made very close to each other in the mouth.

Pronunciation is a key part of using English to communicate. And if you're not sure how to say a word, it can impact your confidence and fluency.

If you don't have these two distinct sounds in your own language, it may be hard for you to tell them apart - and even harder for you to make them clearly. This blog is designed to help you hear and say these two sounds.

When you look at the IPA script for these words, shown in the slash brackets, you can see clearly that the vowels are pronounced differently:

cap /kæp/

cup /kʌp/

Practising these sounds in isolation, and watching yourself in a mirror while you do so, will help you learn the difference between these vowels. You should see a slightly wider mouth for the sound /æ/ and a narrower mouth for /ʌ/.

You will find these IPA spellings - along with an audio sample - in learners' dictionaries, like the Cambridge Dictionary so you can always check exactly how a word should be pronounced.
