Kein, keine, keinen

What's the difference? When do I use them?

When do I use these instead of words like 'nie' or 'nicht'?

Many thanks for your help!

"kein" means "none" or "no". "Ich habe keine Ahnung" = "I have no idea". To understand when to use which version of "kein" you have to understand German cases. Internet has tons of resources on that, for example here:

"nie" is short of "niemals" and means "never"

"nicht" is like "not" in English, "Ich weiƟ nicht." = "I don't know."

Please, read the grammar "Tips and notes" in Duolingo's web version ( You can find them in the lessons web page of each skill, that contains new grammar.
