Difference between ein and einen

Hello everyone! Although the article for "Kaffee" is "der", I can't understand why in the sentences the word "ein" is not used instead "einen" is used! Which one of the below sentences is correct? If both are correct, then what is the difference? Could someone help me with this issue? Ich will einen Kaffee Ich will ein Kaffee

Hi Behzad, "Ich will einen Kaffee" is the correct sentence. For the accusative case and male Nouns 'ein' turns into 'einen'. Also some masc. nouns add -en or -n in the accusative. Please let me know if you need more examples for the accusative case. Hope it helps! Paul

Thank you very much for your help Sir! But could you elaborate on the issue (adding -en or -n in the accusative case)? Sincerely, Behzad

Lessons 6.6 and 6.7 explain the accusitive and dative cases. What I found useful was to print off some truth tables that you can easily find on the internet that list all the ending for articles based on gender and case. I can't say that it makes sense. Maybe Paul disagrees, but there is just some stuff you have to memorize in German although there are some guidelines and general rules.

Thanks a lot Mr. Bryon! Sincerely, Behzad
