The vowel eo doesn’t form a final on its own. It is always combined with another vowel or an ending consonant to form a final. Also, note that the vowel eo is not produced by combining the vowel e and the vowel o. It is a sound different from both of them.

Step 1  Listen to the vowel eo.

Step 2  Listen and repeat. Pay attention to your mouth shape. Use a mirror to check it if needed.

Tongue Position: Raise the center of your tongue toward your hard palate a little.
