@ThreeSigma "countability" would be the property, that a meaningful "cardinality" exists, and the "cardinality" would be the actual number of items.The difference between "how much" and "how many" is also not, if a natural number would be reasonable answer, but if that's the answer, that I expect.How much potatoes? "1kg" or "5 potatoes" would be valid answers.How many potatoes? "5 potatoes" or just "5" would be valid, "1kg" would not be valid.@argv_minus_one @StefanMuelller
