A German Dictionary is a reference book that provides definitions, translations, and explanations of words in the German language. It helps users understand the meanings of words, their correct usage, and grammatical information such as gender and conjugation. These dictionaries can be bilingual, offering translations between German and other languages, or monolingual, focusing solely on German definitions. They are useful for students, travelers, and anyone looking to improve their German language skills. Many dictionaries also include additional features like example sentences and pronunciation guides.
