Selfish shellfish
Two words that are almost mirror images. “Selfish” goes S, then SH at the end. “Shellfish” goes SH, then SH again, with an L and F in between. Most people manage it once, but by the third repeat they say “shelfish sellfish”.

Why the sounds swap
Look at the order: S-L-F-SH, then SH-L-F-SH. The middle of both words is the same, L and F, so your brain treats them as one word with two starts. Under speed it often chooses the wrong one: “shelfish shellfish” or “selfish selfish”.
The difference between S and SH is small. For S the tongue is forward, close to the ridge behind the teeth, and the lips are relaxed. For SH the tongue moves back and the lips round and push out. If the lips stay still, the two sounds blur.
There is also a cluster in the middle, LF. The tongue touches the ridge for L, then the lower lip moves to the upper teeth for F. When rushed, the L often drops: “sefish shefish”.
How to learn it
Say the two words very slowly, one at a time. Think of “self” and “shell” as the key parts: “self-ish”, “shell-fish”. Keep the meaning in mind, a shellfish that only cares about itself, and the order stays clearer.
Then watch your lips. Smile slightly on the S of “selfish” and push your lips forward on the SH of “shellfish”. Exaggerate it at first. It feels silly, but the movement is what keeps the sounds apart.
Repeat the pair five times on one breath, slowly. When that is clean, speed up a little and try again. If you hear the swap, go back to one slow round before you continue.
