Identify the phonetic symbol of the underlined sounds : Thin, Method, Author

Question

Accepted Answer

The correct answer for the phonetic symbol of the underlined sounds in the words "Thin," "Method," and "Author" is Option 1: θ.

1. **Explanation for Option 1 (θ):**
   - The symbol "θ" represents the voiceless dental fricative sound in the International Phonetic Alphabet (IPA). This sound is produced by placing the tip of the tongue against the upper teeth and forcing air through the narrow gap, creating a friction-like sound.
   - In the word "Thin," the initial sound is the voiceless dental fricative, represented by "θ."
   - In the word "Method," the "th" sound is also a voiceless dental fricative, represented by "θ."
   - In the word "Author," the "th" sound is again a voiceless dental fricative, represented by "θ."
   - Therefore, Option 1 is correct because it accurately represents the phonetic sound of the underlined "th" in all three words.

2. **Explanation for why other options are incorrect:**
   - **Option 2 (tʃ):** This symbol represents the voiceless postalveolar affricate sound, as in the word "chop." It is a combination of a "t" sound followed by a "sh" sound. This is not the sound present in "Thin," "Method," or "Author," making it incorrect.
   - **Option 3 (F):** This symbol does not correspond to any standard phonetic symbol in the IPA. It might be confused with the symbol "f," which represents the voiceless labiodental fricative sound, as in "fish." The "th" sound in the given words is not a labiodental fricative, so this option is incorrect.
   - **Option 4 (^):** This symbol does not represent any specific sound in the IPA. It is not associated with the "th" sound in any of the given words, making it an incorrect choice.

In conclusion, Option 1 (θ) is the correct phonetic symbol for the underlined sounds in "Thin," "Method," and "Author," as it accurately represents the voiceless dental fricative sound present in these words.
