Explaining the difference between ordinal and cardinal numbers when they mean the same thing.

My sister became twelve years old yesterday.

Yesterday was my sister's twelfth birthday.


How do you explain why you use a cardinal number for the first sentence and ordinal for the second and why these are not interchangeable. Thank you!

I don't understand your problem, really, but the first is cardinal + unit, while the second in is ordinal (adjectival) + noun.

anonymous why these are not interchangeable.

How would you presume to do that?
