denunzieren

Etymology
From.

Verb

 * 1) to denounce, to inform against
 * 2) to denounce, to stigmatise
 * 1) to denounce, to stigmatise

Usage notes

 * In both senses, the German verb implies that the denouncing is done for base motives and not for the sake of justice. Therefore, while German can usually be translated with “to denounce”, the reverse is often not the case.
