The word is derived from the verb 'verrücken' (to move something out of place), which means 'to move something from its proper place.' So 'verrückt' (crazy) metaphorically describes a state in which the mind or things are no longer in their normal place.

Could you please move the table a little?
The expression 'jemanden verrückt machen' (to drive someone crazy) is very common. It means to make someone very nervous, angry, or impatient.

'Verrückt' (crazy) is often intensified with adverbs such as 'total' (totally), 'völlig' (completely), or 'komplett' (completely) to express intensity.
Die Party gestern war total verrückt.
The party yesterday was totally crazy.
When you want to express that you are very enthusiastic about something or someone, you use the fixed construction 'verrückt sein nach' (to be crazy about) followed by the dative.

The literal meaning 'geisteskrank' (mentally ill) is outdated and is considered insensitive today. In modern language, neutral terms such as 'psychisch krank' (mentally ill) are used instead.

He suffers from a mental illness and is receiving treatment.

'toll' and 'verrückt' can both express strong feelings in casual language, but they usually do not mean the same thing. Today, 'toll' normally means 'very good' or 'great'. 'verrückt' more often describes something strange, unreasonable, extreme, or chaotic. In 'verrückt nach etwas' (crazy about something), it can also mean strong enthusiasm. Learners may confuse the words because 'toll' could also mean 'insane' in the past, and because both words can sometimes sound very strong. In modern everyday language, the rule is: use 'toll' for positive praise, and 'verrückt' more for something strange or extreme.
