sell vs shell: hear and say the difference
sell and shell are identical except for one sound: sell has the s sound, /s/, and shell has the sh sound, /ʃ/. S uses a narrow groove at the tip of the tongue with the lips spread; SH slides the whole tongue back a centimetre, widens the channel and pushes the lips forward.

Why this pair is hard
Bengali's main sibilant is a sh-type sound, so English S often comes out hushed. Tamil, Telugu and most Spanish varieties have no sh and substitute s or ch. Japanese and Korean turn s into sh automatically before an i, so 'see' and 'she' blur in one direction only. Mandarin has a retroflex sh that makes the English one sound darker.
