What is the name for the most common, typically unstressed vowel sound in English?

• A. Phonotactics
• B. Diphthong
• C. Schwa
• D. Polysemy

Answer: (C)

Schwa is the name for the most common, typically unstressed vowel sound in English. It’s a neutral, mid-central vowel that tends to appear in unstressed syllables, often realized phonetically as /ə/ (and /ɚ/ in American English after consonants). Because English tends to reduce vowels in unstressed positions, the schwa shows up in many everyday words regardless of how the letters are written, such as the first syllable in “about” or the second syllable in “banana.” It’s not a diphthong, which involves a glide between two vowel qualities, and it isn’t about word meanings or sound sequences, which are related to other concepts. So the common unstressed vowel sound is schwa.
