Question 58

A, C, and E contain diphthongs.

Words A (Boy), C (Buy), and E (Coin) all feature diphthongs, which are complex vowel sounds that begin with one vowel sound and glide into another within the same syllable.

A) Boy

This word contains the diphthong /ɔɪ/, which starts with the vowel sound in "thought" and glides to the vowel sound in "sit." This combination of sounds makes "Boy" a clear example of a word with a diphthong.

B) Mother

"Mother" does not contain a diphthong; instead, it features a single vowel sound /ʌ/ followed by the consonant sounds. The absence of a gliding vowel sound disqualifies it from being categorized as having a diphthong.

C) Buy

The word "Buy" includes the diphthong /aɪ/, which starts with the vowel sound in "cat" and glides to the vowel sound in "bit." This makes it another valid example of a word that contains a diphthong.

D) Apple

"Apple" lacks a diphthong as it contains the short vowel sound /æ/ followed by a consonant cluster. There is no gliding between vowel sounds in this word, making it not applicable for diphthong classification.

E) Coin

"Coin" features the diphthong /ɔɪ/, similar to "Boy." It begins with the rounded vowel sound and transitions into the short vowel sound, confirming it as a word with a diphthong.

Conclusion

In summary, the words "Boy," "Buy," and "Coin" all contain diphthongs, demonstrating the characteristic gliding of vowel sounds. In contrast, "Mother" and "Apple" do not have such sounds, as they consist of single vowel sounds without any glide, thus affirming that only the selected options are correct.
