What is vowel height?

• A. The lateral movement of the tongue
• B. The horizontal tongue position
• C. The lip rounding
• D. The vertical position of the tongue during articulation, categorized as high, mid, or low.

Answer: (D)

Vowel height describes how high the tongue is in the mouth during articulation, and vowels are categorized as high, mid, or low based on this vertical position. This vertical placement is what sets apart vowels like the high front vowel in beet from a lower vowel in bat, helping distinguish meaning in many languages. Other features you might hear about—how far the tongue sits from the front of the mouth (frontness/backness) or whether the lips are rounded—describe different aspects of vowel quality, not height. Lateral movement of the tongue isn’t the defining factor for vowels, and lip rounding pertains to rounding rather than vertical tongue position. So the vertical position of the tongue during articulation, categorized as high, mid, or low, is what defines vowel height.
