Specialization means to become an expert in one particular thing. For example, a doctor might specialize in heart surgery or a chef might specialize in making desserts. It's important to understand that specialization is a way for people to become very good at something specific, which can be helpful in their careers or hobbies. So, if you're talking about someone's job or interests, you might use the word specialization to describe what they're really good at.
