Questions & Answers about Ich brauche einen Laptop, aber ich habe kein Geld.
Why is it einen Laptop and not just ein Laptop?
Laptop is a masculine noun (der Laptop). Because it receives the action of the verb brauche (to need), it is the direct object and takes the accusative case. In the accusative case, the masculine article ein changes to einen.
If both verbs use the accusative case, why doesn't kein Geld get an -en ending like einen Laptop?
The ending depends on the gender of the noun. Geld is a neuter noun (das Geld). In the accusative case, only masculine articles change. Neuter and feminine articles stay exactly the same as they are in the basic subject (nominative) case. So, the neuter negative article remains kein.
Why use kein Geld instead of nicht Geld to say "no money"?
Does the word aber change the word order in the second half of the sentence?
