No matter how many years you have spent learning English or teaching it, there will always be a word that catches you off guard. That is completely normal. It happens to everyone, from new teachers to experienced professionals. Language is alive. It shifts, expands, drops old expressions, brings back forgotten ones, and constantly creates new vocabulary.

So if a student asks about a word you cannot recall right away, or one you have never come across before, there is no reason to panic. In fact, being able to admit that calmly shows something important: learning a language is not a stage you finish, but an ongoing process. That is true for students, and it is just as true for teachers. At this point, many people start asking the same question: how many words do you actually need to know for each level of English? And teachers often ask an even sharper one: how many words should you know to feel confident enough to call yourself an English teacher?

In this article, I want to break that down in a practical way and show what kind of vocabulary really matters for an English teacher, and how to keep developing it without burning out.

• Tips for teachers

Have you ever had one of those evenings when you still had an English lesson ahead of you, your students were tired, and you needed something fresh that would immediately bring energy back into the room? I know that feeling very well. More than once, the right YouTube video saved a lesson for me. It solved the motivation problem, gave me a strong listening task, and opened the door to a meaningful speaking activity at the same time.

“York, aren’t you worried about the future of teaching English? What if artificial intelligence replaces teachers soon?” I hear this question from colleagues at almost every conference or professional meetup. And every time the conversation leads to the same conclusion: the future of English language teaching is not about teachers disappearing. It is about new roles, modern educational technology, and an honest conversation about what we as educators must change and develop in ourselves.

Have you ever had this happen? The lesson feels like a win, students were engaged, the timing worked, the activities flowed—and then one honest student comment knocks you off balance for the rest of the evening. For a long time, student feedback for English teachers felt intimidating and strangely personal to me. That changed when I stopped treating feedback as a verdict and started using it as a practical tool. Now student feedback in ELT helps me refine lessons with confidence—calmly, step by step, without overthinking every detail.

In a hospital emergency room, communication is never “just practice.” It is about clarity, safety, and responsibility. That is why English for Medical Purposes is one of the most promising and well-paid niches for English teachers who want to specialize and grow professionally.

Teaching specialized English (ESP) requires deeper preparation than teaching General English. You need to understand the professional context of doctors, nurses, and medical staff, typical communication scenarios, essential terminology, and—most importantly—how to turn all of this into practical, scenario-based lessons rather than simple vocabulary lists. This level of expertise deserves higher rates and professional recognition, because you are solving real workplace communication problems.

In this guide, I’ll show you how to position yourself in the medical English teaching niche, what skills and materials you need to start, how to integrate ESP and CLIL into your lessons, and how to expand medical vocabulary systematically—without overwhelming your students.
