ch sound
Rule Core
The ch sound is a prominent English consonant digraph, most commonly pronounced /tʃ/, a voiceless affricate. It combines a stop and a fricative, typically appearing at the beginning or middle of words such as chair or brunch.
Articulation Guide
Place the tongue tip just behind the upper alveolar ridge. Begin with a brief stop like /t/, then release immediately into a /ʃ/ friction. Lips are slightly rounded; airflow is strong and unvoiced.
Word Analysis
- brunch: /brʌntʃ/, final ch must be crisp and complete.
- chairperson: /ˈtʃeərˌpɜːrsn/, initial ch sets the rhythmic tone.
- challenging: /ˈtʃælɪndʒɪŋ/, maintain smooth transition into /l/.
Pitfall Alert
Not all ch spellings sound /tʃ/. Greek-origin words (chorus) use /k/, while French-origin words (machine) use /ʃ/. Lexical awareness is essential.
