Needn't vs No need to - English In A Minute

Hi, everybody. I'm Sam, and in this lesson

안녕하세요 여러분. 저는 Sam이고 이번 강의에서는

I'm going to talk about 'need'. Do you know

'need'에 대해 이야기할 것입니다.

the difference between 'needn't' and 'not need to'?

'필요하다'와 '필요없다'의 차이를 아시나요?

Look at these two sentences in the present - is the

현재의 이 두 문장을 보세요.

meaning the same or different?

의미가 같은가요 아니면 다른가요?

'You don't need to worry about the exam,

'시험 걱정할 필요 없어,

you've studied lots.'

공부 많이 했잖아.'

'You needn't worry about the exam,

'너 시험 걱정할 필요 없어.

you've studied lots.'

공부 많이 했잖아.'

They're the same right? Maybe 'needn't'

똑같은거 맞죠? 'needn't'가

is a little bit more formal, but the meaning

좀 더 형식적일 수도 있지만

is that there is 'no necessity for you to worry'.

'걱정할 필요가 없다'는 의미입니다.

Now look at these two sentences in the past:

이제 과거의 이 두 문장을 보십시오.

'He didn't need to worry about the exam.

'그는 시험에 대해 걱정할 필요가 없었습니다.

He had already passed the course.'

그는 이미 과정을 통과했습니다.'

'He needn't have worried about the exam.

'그는 시험에 대해 걱정할 필요가 없었습니다.

It was really easy.'

정말 쉬웠어.'

These are different! In the first sentence,

이들은 다르다! 첫 번째 문장에서

he had already passed the course, so he knew

그는 이미 과정을 통과했으므로

he 'didn’t need to' worry.

걱정할 필요가 '없다'는 것을 알았습니다.

In the second sentence, he didn't know the

두 번째 문장에서 그는

exam was going to be easy, so he was worried,

시험이 쉬울 줄 몰라서 걱정했지만

but he 'needn't have been'.

'그럴 필요는 없었다'.
