Definition from Wiktionary, the free dictionary
- (relative) whose, of which (genitive of der, das).
- (demonstrative) his, its, the latter's (genitive of der, das)
- Since dessen and deren do not occur in normal vernacular German, unexercised users of literary German often make grammatical mistakes in using these pronouns. The most common one of them is to use dessen where deren would be correct (or occasionally vice versa).
- Another common mistake is a double-genitive construction such as the following: Nach dem Tod seines Vaters wurde er Leiter dessen Betriebes. — “After the death of his father, he became the director of the latter’s company.” Since dessen/deren are substantival pronouns, not determiners, they can never have another genitive following them. The correct phrase reads: Nach dem Tod seines Vaters wurde er Leiter von dessen Betrieb. The mistake is due to hypercorrection, i.e. the exaggerated desire to avoid the preposition von (“of”).
