More Minimal Pairs
As you may remember, minimal pairs are two words that sound very, very similar. In fact, they usually have only one sound that is different. An example of this is “van” and “fan” where only the /v/ sound and the /f/ sound are different (and sometimes difficult for non-native speakers to both hear and pronounce).
Check out this site to listen to and practice some more minimal pairs. You can listen and then try to guess which word is being said.
