Here's why:
* Phoneme: A phoneme is the smallest unit of sound that distinguishes one word from another.
* "Church" is pronounced with the following phonemes: /tʃɜːrtʃ/
Let's break it down:
1. /tʃ/: This represents the "ch" sound.
2. /ɜː/: This represents the "ur" sound.
3. /r/: This is the third phoneme, representing the "r" sound.
4. /tʃ/: This represents the "ch" sound again.
Therefore, the third phoneme sound in "church" is /r/.
