French ch
Core Rule
In French, the letter combination ch is most commonly pronounced as the voiceless postalveolar fricative /ʃ/, similar to English sh. This reflects a historical sound change in French. A limited set of words of Greek origin pronounce ch as /k/ and must be memorized individually.
Articulation Guide
For /ʃ/, retract the tongue slightly toward the post‑alveolar region without touching it. Keep the lips gently rounded. Air flows continuously through a narrow channel, creating friction without a stop or burst.
Word Analysis
- brochure /bʁo.ʃyʁ/: medial ch consistently sounds /ʃ/.
- champagne /ʃɑ̃.paɲ/: initial ch → /ʃ/, followed by a nasal vowel.
- chef /ʃɛf/: same /ʃ/ sound; shorter and tenser than in English.
Pitfall Guide
Do not confuse French ch=/ʃ/ with English ch=/tʃ/. Also watch for Greek-derived words like chaos or chorale, where ch is pronounced /k/.
