CH vs SH

chair vs share: hear and say the difference

chair and share are identical except for one sound: chair has the ch sound, /tʃ/, and share has the sh sound, /ʃ/. CH starts with the tongue stopping the air against the ridge and then releases into the hush; SH never stops anything — it is the hush on its own.

Who merges this

Why this pair is hard

French and European Portuguese spell ch as the plain hush, so 'cheap' comes out as 'sheep'. Spanish has ch but no sh, so the error runs the other way and 'she' becomes 'chee'. Arabic varieties without an affricate use sh for both.
