Morphology

sound + as + a + bell

The adjective 'sound' (in good condition) combined with the simile 'as a bell' is compositionally predictable: the comparison to a bell implies a clear, intact quality that strengthens the meaning of 'sound.' This follows standard English comparison patterns, so a B1 learner who knows the constituent words can infer the meaning 'in perfect condition / functioning well.'

Etymology

Sound as a bell paints the picture of a clear bell that rings perfectly and loudly, with no cracks or problems. That's why calling something sound or sound as a bell means it is 'in perfect condition' or 'reliable'.
