Which place of articulation uses the lower lip and upper teeth, as in /f/ and /v/?

• A. Labiodental
• B. Bilabial
• C. Alveolar
• D. Palatal

Answer: (A)

This question tests where in the mouth a sound is formed, called the place of articulation. The labiodental place uses the lower lip and the upper teeth. When producing sounds like /f/ (voiceless) and /v/ (voiced), the lower lip lightly touches or comes close to the upper teeth and air streams through the small gap, creating friction that shapes the sound.

Other places involve different constrictions: bilabial uses both lips (as in /p, b, m, w/), alveolar uses the tongue tip or blade against the ridge just behind the upper teeth (as in /t, d, s, z, n/), and palatal uses the body of the tongue against the hard palate (as in /ʃ, ʒ/ and similar sounds).
