I practice German cases sentences to learn by heart, but I have stumbled across a form that I don't think it is so common.
Ich sprach mit den kleinen Kindern.
In this sentence, the plural form of Kind reflects the case with an n. I don't think I have seen so many n at the end of words in plural dative.
But if it is to happen with a limited set of words, could you you give me some kind of rule to know which words get an n at the dative plural?
What I guess more or less, it's that plural in er should append and n. Is it all?
