Explanation
Understanding Negation
In German, there are two primary ways to say 'not' or 'no': nicht and kein. Knowing which one to use depends on what exactly you are negating. If you want to negate a noun that has an indefinite article (ein/eine) or no article at all, you use kein. It functions much like the English word 'no' (e.g., 'I have no time').
When to use 'kein'
Use kein for nouns. It changes its ending just like the indefinite article ein. For example, in the accusative case, 'ein Buch' becomes 'kein Buch', and 'eine Tasche' becomes 'keine Tasche'. It is the perfect choice for sentences like 'Ich brauche kein Handy' (I don't need a/any phone).
When to use 'nicht'
Use nicht to negate verbs, adjectives, adverbs, or nouns that have a definite article (der/die/das). If you are negating a whole sentence or a specific action, nicht is your go-to word. For example, 'Ich verstehe nicht' (I don't understand).
Word Order with 'nicht'
In simple sentences, nicht usually comes at the end: 'Ich warte nicht'. however, if there is a second part of the verb (like an infinitive or a prefix) or a specific location/adjective, nicht stands before that element: 'Ich möchte nicht warten'.

Common Mistakes
When negating a noun with an indefinite article (ein), you must use 'kein' instead of 'nicht ein'.
In a simple German sentence, the verb stays in the second position, and 'nicht' typically follows it.
'Geld' is neuter (das Geld), so the ending for 'kein' must match the neuter grammatical gender.
