Sounds which occupy an intermediary position between vowels and all other consonants are called a _____?

• A. Approximant
• B. Vowel
• C. Diphthong
• D. Consonant

Answer: (A)

Approximants are consonants produced with a relatively open vocal tract, so air flows smoothly without the turbulence of most other consonants. That openness gives them a vowel-like, flowing quality, placing them in a middle ground between vowels (which are the most open and vowel-like sound), and more constricted consonants that create noticeable friction or stopping of the air. In practice, sounds like the English w and y (as in wet or yes) are classic examples of approximants—they behave like consonants in how they function in speech, but their articulation is so open that they feel almost vowel-like. The other options don’t fit this middle ground: a vowel is the nucleus of a syllable with a fully open vocal tract; a diphthong is a vowel sound that shifts quality within a single syllable; a consonant is a broader category that doesn’t capture the vowel-like openness of approximants.
