1. Business English or Professional English: This focuses on using English effectively in a professional context, including communication skills for meetings, presentations, negotiations, writing reports, and emails.
2. Advanced English: This refers to a higher level of English proficiency, often achieved through formal study or extensive exposure to the language. It includes a deeper understanding of grammar, vocabulary, and cultural nuances.
3. "Smart" as a colloquial descriptor: People might use "smart" informally to describe English spoken by someone who is intelligent or knowledgeable. However, this is subjective and not a technical term.
To be clear, "English" itself encompasses all levels of proficiency, from basic to advanced. There is no separate "Smart English" language or dialect.
