In today’s tip, we’ll look at a simple mistake that even native speakers make on occasions. What is correct: зачем or за чем? What is the difference? We shall soon see.
| зачем, a single word, is an adverb, and carries the meaning of why? for what reason? |
| Верочка, ты и так красива! Зачем краситься? Verochka, you’re so beautiful! What’s the point of putting on make-up? |
| Зачем бороться? Всё уже решино. Why fight? Everything’s already been decided. |
| за чем is a combination of the preposition за, and что in the instrumental case. Its meaning will vary based on context. |
| –За чем эта очередь? –Это очередь за едой. What is this line for? [to receive what?] -It’s a line for food. |
| –За чем находится магазин? –Он находится за аэропортом. -What is the store behind? [location] -It’s behind the airport. |
