From the words lettered A to D, choose the word that contains the sound represented by the given phonetic symbol.
/ ð /
Answer Details
The phonetic symbol /ð/ represents the voiced dental fricative sound, which is produced by placing the tip of the tongue between the teeth and forcing air through the narrow gap, while the vocal cords vibrate.
Out of the given options, only one word contains the sound /ð/: "smooth." The "th" in "smooth" is pronounced with the voiced dental fricative sound /ð/.
Therefore, the correct answer is "smooth."
