Questions & Answers about geupjeonggeoreul hamyeon gamjeomi issseupnida.

What does 급정거 mean exactly?

급정거 is a noun meaning a sudden stop or sudden braking.

• 급 = sudden, urgent
• 정거 = stop

In real usage, 급정거를 하다 means to make a sudden stop / to brake suddenly.

So in this sentence, 급정거를 하면 means if you make a sudden stop.

Why is it 급정거를 하면 and not just 급정거하면?

Because 급정거 is being used as a noun here, and Korean often makes verbs with noun + 하다.

So the structure is:

• 급정거 = sudden stop
• 급정거를 하다 = to do a sudden stop, to brake suddenly

The 를 marks 급정거 as the object of 하다.

So:

• 급정거를 하면 = if you do a sudden stop

You may also see 급정거하다, which is essentially the same idea in a more dictionary-like verb form. But noun + 를 하다 is very common and natural.
