ch /tʃ/

Rule Core

In English phonics, the letter combination ch most commonly represents the voiceless affricate /tʃ/, as in chair. It combines a stop and a fricative: air is fully blocked, then released with friction. This pronunciation dominates in words of Germanic origin and forms a foundational decoding rule.

Articulation Guide

Place the tongue tip just behind the upper alveolar ridge, with the front of the tongue slightly raised. Lips are gently rounded. Build up air pressure, then release it sharply. The vocal cords remain inactive.

Word Analysis

• bachelor /ˈbætʃələr/: ch clearly signals /tʃ/ in the medial position.
• beach /biːtʃ/: final ch must be crisp, not weakened.
• channel /ˈtʃænəl/: initial ch is almost always /tʃ/.

Pitfalls

Avoid overgeneralizing ch as /k/ or /ʃ/. The defining feature of /tʃ/ is the stop-plus-friction sequence.
