Subspecialties are specific areas of expertise within a broader field. For example, in medicine, a doctor may be a general practitioner but can choose to focus on a subspecialty like pediatrics or cardiology. This allows professionals to gain in-depth knowledge and skills in a particular area, providing better care and specialized services to patients. In other fields, such as engineering or education, subspecialties also exist. An engineer might specialize in civil engineering or software engineering, while an educator could focus on special education or early childhood education. These subspecialties help individuals tailor their careers to their interests and the needs of their communities.
