The key difference between as und like is their primary function: as describes the role, job, or purpose of something, while like indicates similarity or comparison. Think of as meaning ‘in the role of’ or ‘in the capacity of’, and like meaning ‘similar to’ or ‘in the same way as’. For example, you might work as a doctor (your profession), but you could also say someone looks like a movie star (a comparison). Mastering this distinction is crucial for B2 English learners. It helps you express ideas precisely and avoid common errors. This guide will clarify when to use each word, helping you improve your accuracy for both speaking and writing, and preparing you for exams like the B2 First.
