Identify the Different 'ch' Sound in English Words

The question asks us to identify the word among the given options where the underlined letters 'ch' represent a sound that is different from the sound represented by 'ch' in the other words.

In English, the letters 'ch' can represent several different sounds, most commonly the /tʃ/ sound (as in 'chair'), the /k/ sound (as in 'school'), or sometimes the /ʃ/ sound (as in 'machine'). We need to examine the pronunciation of 'ch' in each provided word.

Analyzing the 'ch' Sound in Each Word

Let's break down the pronunciation of the underlined 'ch' in each option:

• catch: In the word 'catch', the 'ch' is typically pronounced with the /tʃ/ sound. This is a common pronunciation for 'ch', especially at the end of a word following a short vowel sound or after 't'.
• watch: Similarly, in the word 'watch', the 'ch' is also pronounced with the /tʃ/ sound. This follows the same pattern as 'catch'.
• match: In the word 'match', the 'ch' is again pronounced with the /tʃ/ sound, consistent with 'catch' and 'watch'.
• patriarch: In the word 'patriarch', the 'ch' is often pronounced with the /k/ sound, as in words like 'monarch' or 'stomach'. This pronunciation comes from its Greek origin.

Comparing the 'ch' Sounds

By analyzing the pronunciation, we can see the sounds represented by 'ch' in each word:

• catch: /tʃ/
• watch: /tʃ/
• match: /tʃ/
• patriarch: /k/

The sound of 'ch' in 'catch', 'watch', and 'match' is the same /tʃ/ sound. However, the sound of 'ch' in 'patriarch' is the /k/ sound, which is different.

Conclusion

Based on the pronunciation analysis, the word where the underlined alphabets 'ch' have a different sound compared to the others is patriarch.
