SH Isn't CH: Two Sounds Polish Blends

Research on Polish learners of English points to consonant substitutions as one of the biggest sources of a noticeable accent — and the SH/CH pair is a common one to slip on. English SH, as in 'sheep' or 'wash,' is a smooth, continuous hiss with no tongue-tap at the start. English CH, as in 'cheap' or 'watch,' begins with a quick stop before the hiss, almost like a tiny click leading into the sound. When these two blend together, 'sheep' and 'cheap,' or 'wash' and 'watch,' can become confusingly similar to American listeners. Try this: say 'sheep' while keeping your tongue still and just letting air hiss out smoothly — no tapping. Then say 'cheap,' starting with a brief stop before the hiss begins, almost like a light 't' sneaking in first. Practice the pair 'wash/watch' the same way, five times each. This one small tongue-timing habit can noticeably sharpen how clearly you're understood.
