It's important to correctly pronounce the word "exceptional" if you're speaking English. Here's how:
Start by saying the "E" sound. Keep the tongue flat against the bottom of your mouth and make a short, sharp sound.
Next, say the "X" sound. Open your mouth wide and form your lips into an "O" shape. Gently force air out of your mouth and make a sharp sound.
Then, say "cep". The "c" sound is a soft "s" sound. The "e" is a short, sharp sound and the "p" sound is made by pushing air out of your mouth and making a popping sound.
Finally, say the "shun" sound. This is made by combining the "sh" sound with the "un" sound. Start by making a "sh" sound. The "u" sound is a long, drawn out sound and the "n" is a short, sharp sound.
Put it all together and you have "excep-shun-al". Practice saying it out loud and you'll have it mastered in no time.
