'Verachten' (to despise) is an inseparable verb. The prefix 'ver-' always stays attached to the stem 'achten' (to respect/pay attention to). It reverses the meaning of 'achten' (to respect) into its opposite.

She despised him for his lies.
The verb 'verachten' (to despise) always requires a direct object in the accusative. You always despise 'jemanden' (someone) or 'etwas' (something).

'Verachten' (to despise) is a very strong word that expresses deep dislike. It is mainly used in written language or in formal contexts.

In the meaning of 'sich über etwas hinwegsetzen' (to disregard/defy something), 'verachten' is often combined with abstract concepts such as 'den Tod' (death), 'die Gefahr' (danger), or 'die Regeln' (the rules).

to pay attention / to respect
'achten' and 'verachten' are opposites when it comes to one's attitude toward a person or thing. 'achten' means to respect and value someone or something. 'verachten' is much more negative: you look down on someone or feel deep dislike. Learners may confuse the words because of their similar form. The important point is: 'verachten' does not simply mean 'not pay attention to'. It means strong contempt. For normal respect, use 'achten'; for a very negative attitude, use 'verachten'.

The teacher does not despise anyone just because they make mistakes.
