Hello, I'm nail and Joining Me is Katherine.

Hi Katherine.

Hi Nia with House story today.

Today's story Neil is all about recycling, recycling.

I love talking rubbish.

Let's find out some or from this BBC news bulletin.

A Californian companies made history by launching a used rocket back into space, traditionally rockets who used once before being scrapped.

But Space X has developed a way of landing its boosters safely on Earth.

So an American company its name is Space six is trying to revolutionise based travel.

In fact, it wants to send people to live in space.

But of course that's going to be very expensive.

So they found a way to save money by using rockets more than once.

Now, usually a rocket goes to space.

It doesn't come back.

If anything does come back, it's burned, but they've actually found a way to have a rocket come back from space and go out again.

Okay, How interesting you've been Ah, searching the news websites for this story.

And you found three words that are being used to talk about this?

Yes.

We have reusable launches on milestone.

Okay, reusable launches and milestone.

What's your first headline?

Okay, so we'll go to the BBC news website and our headline is successful.

Space six Reusable rocket.

So reusable.

Meaning simply able to be used again.

Absolutely.

And the key thing in this word is the prefix re.

Now, a prefix goes at the beginning of the word.

The two letters Ari mean again.

So we can.

This rocket is being reused.

We can talk about redo if you do something and then you do it again, you read.

Do it.

Yeah.

And, um, I saw on your desk earlier, um, lunch.

We looked like lunch, but it looked like yesterday's lunch.

Well, it was yesterday's dinner.

I made a lot of it.

I brought some of it to the work in a container on I'm going to reheat it.

That means heated again and have it for my lunch.

They're going to preheat the oven.

I'm going to preheat the oven before for about 15 minutes with nothing in it on.

Then I'm going to reheat my lunch now pre means before, so I preheat the oven means I he's it before I cook with it, as opposed to re, which means again, he's again.

So there's a difference in meaning between re and pre, but also a difference in tone.

Isn't there?

I've seen in this story pre law pre use.

Yes, abused, absolutely so pretty use and reusability them both.

When we're talking about this story, reuse means use it again.

Pre used means it was used before the tone.

I guess if you say something's pre used, it kind of has the idea of, Well, it's Bean.

It's Bean made ready.

In a way, it's not quite a bit more positive than reuse.

For example, this word that around quite a lot these days, pre loved, free, loved Neil.

Yes, you're absolutely right now I am trying to make you buy my old mobile phone, which some people say it's a little bit old.

It doesn't work very well.

One of the keys is missing.

I say it's pre loved, not second hand.

No, it's pretty love, which means somebody loved it before.

It's a bit of a marketing device because in fact, To be honest, it's not in the best of conditions.

I was going to say if you loved it that much, You keeping it, wouldn't you?

Okay, let's look at our next headline.

Okay, so we're looking at ABC now.

The headline is Space six launches its first recycled rocket in historic leap.

So launches here meaning to put a spacecraft into space?

Absolutely.

The original meaning of launch is for a boat which is on land.

And then when we put the boat into water and sail on it, that's action is called a launch or to launch as a verb on.

The spaceship has been taken off.

The rocket was taken from the land and put into space.

So start to travel.

I see.

Now, Catherine.

Yes?

You're looking confused, as usual.

I'm a bit confused about this because I saw this word in connection with a party.

So I was invited to a launch part.

But it had nothing to do with ships and nothing to do with spaceships.

What was the party for them?

I was for a website.

A new website?

Yeah.

Okay.

So a launch in often in marketing or commercial terms, is when we get a new product or service on make it available to the wider public for the first time.

So a party often we have a party to celebrate.

The fact that there's new product or services is available to everyone.

It's called a launch on the bank's part of the thing that connects all of these meanings.

Of this word is the idea of putting something into motion.

Getting it started getting something started for the often for the first time, our final headline.

Okay, and we're now going to City A M.

The headline is Elon Musk's Space X reached a milestone in reusability yesterday when it successfully relaunched a segment of one of its Falcon nine rockets and we've got to grease their reusability, which is a fabulous known on relaunched meaning.

It was launched again when a wonderful headlines got all of our words, including Milestone, which is an event which marks an important stage in a process.

Absolutely so.

If the ultimate aim of Space X is to get a lot of people going to space for affordable price, getting a rocket back into space for the first time is an important event on we we call that an a milestone.

It's an event that's really significant in a journey or process once again, confused again.

I'm a bit confused because you were walking along, was walking along a country lane.

And I saw this stone.

Yes, and I had to written on it, and I thought that that was a milestone.

And you, you are not wrong, Neil issues.

If you're walking along a country road in particular in the UK, at least you see literally a stone, a piece of stone with some writing on it on the side of the road on That's telling you how far it is to your destination.

Probably the storm would say London to that means your two miles away from London on Have you been walking a long time?

You see that stone?

Use a hooray.

I'm the only two miles from London and you feel happy.

It's a significant event in your journey, and it's an example of how the original meaning of a word this is probably almost never used.

Now very rarely, I would imagine we don't see milestone so often now.

Nowadays, eso the milestone is a stone that says miles, but we use it idiomatic Lee to say an important event has happened in my progress.

So you could say you want to be an architect?

I passed my exams.

That's a milestone in my journey to becoming an architect.

Well, before we recap the vocabulary, we have an important milestone in this program.

We do.

It's the Facebook challenge we've been talking about.

Spacecraft on old fashioned name for a UFO.

That's an unidentified flying object is a flying What a flying.

What is it?

A plate?

Be bowl or see saucer?

What kind of response did we get?

Great response is always near.

Onda Shout out here to Sarah Border, Eva Zoe Lock.

See Andi mistress are met.

Who said it's C to describe a flying object that people say they've seen in this guy that is usually round like a saucer or disc, and that is believed by some people to be a spaceship from another world.

Okay, great.

Well, can you now give us recap of a word from today, please?

I can We hade reusable, able to be used again.

Launched when a spacecraft is put into space on Gmail Stone on event which marks an important stage in a process.
