Pinyin spelling rules
You might think that pinyin has no "rules" other than simply memorizing correctly and then writing out the syllables in the pinyin chart. You'd be wrong! There are quite a number of issues that even native speakers get wrong. Getting them correct makes pinyin easier to read and less likely to cause confusion.
Why Learn the Rules?
Many of the rules of pinyin make pinyin easier to read and harder to misread. Most of these rules are of this type, and we encourage all learners to learn them.
It also helps you judge how well a school or teacher really knows their pinyin. (If they do, they should follow these rules, or at least be aware of them!)
The Key Rules
