Pronouncing the word "cousin" correctly is essential for effective communication in English. Here are a few tips to help you master the pronunciation.

First, make sure you relax your mouth and jaw. Begin by saying the word with the "oo" sound like in "goose". Then, quickly move to the vowel "uh", sounding like "u" in "cut". The final consonant is "z" which should be pronounced with an "s" sound, not a "z" sound.

In summary, the correct pronunciation of the word "cousin" is "koo-suhn". It is important to note that the "s" sound comes before the "uh" sound, not after it.

Practice saying the word "cousin" out loud several times in a row. This will help you get the pronunciation down. It may also be helpful to listen to native English speakers saying the word, so you can mimic the correct pronunciation.

With practice, you should be able to pronounce the word "cousin" correctly with ease.
