Explanation

Central vowels use the middle part of the tongue. The sound [a] is made with the tongue in the center, not front or back. This makes it a central vowel.

Vowels can be front (like [i]), back (like [u]), or central. The [a] sound puts your tongue in the middle position of your mouth.

Tongue position determines vowel types. Knowing where your tongue goes helps you make correct sounds.
