Specialized dictionaries are reference books that focus on specific fields or subjects, providing definitions and explanations tailored to those areas. Examples include medical dictionaries, legal dictionaries, and technical dictionaries, which help users understand terminology unique to those professions or disciplines. These dictionaries often include detailed descriptions, usage examples, and sometimes illustrations to clarify complex concepts. They are valuable resources for students, professionals, and anyone seeking in-depth knowledge about a particular topic, such as medicine, law, or engineering.
