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

What is the difference between cap and cup?

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.
