Common Mistakes

MISTAKE: Thinking that very large numbers are not countable. | CORRECTION: Even if a number is huge, like the number of grains of rice in a bag, it is still countable in principle, even if it takes a very long time.

MISTAKE: Confusing countable quantities with things that are measured, like water or milk. | CORRECTION: Countable quantities are distinct items you can count (like bottles of milk), not the liquid itself (which is measured in liters).

MISTAKE: Believing that only small numbers are countable. | CORRECTION: The size of the number doesn't matter; if you can assign a whole number to each individual item, it's countable.
