Master AT, ON, IN with the TRIANGLE method

2034

Hi. I'm Rebecca from engVid.

By the end of this lesson you will learn how to use three of the most confusing prepositions

in English, and they are: "at", "on", and "in", as applied to time.

Now, if you think you're alone in having problems with these little words, you are not alone.

Many students have difficulty with these words because they're different in their native

languages and probably in yours. Right?

So, what do you do?

Well, keep watching because I have found a solution which has helped many of my students,

and I think it will help you, and that is by using a pyramid or a triangle-okay?-to

learn these three important words.

Let's see how it works.

So, like the triangle: "at" is used in very specific situations, very narrow situations.

For example: "At 5:00", "At 12:30", "At midnight", right?

It's very exact.

It's very narrow.

"On", like the triangle, is a little bit broader and it's used for one day or one date.

For example: "On Monday", or "On January 25th", "On New Year's Day".

Are you with me?

Good. Let's continue.

Now, "in" is the widest of the lot, as you can see, like in the triangle; "at", "on", "in".

So, "in" covers things like months, seasons, years, decades, centuries, and any kind of

For example, we say in English: "In July", "In summer" or "In the summer", "In 2005",

"In the 1960s", "In the 1800s", which was a long time ago, or: "In the past".

We can also say: "In the future", okay?

Because it's also a long period of time.

Did you get that?

So: "at" for very narrow situations; "on" for little bit wider, one day or one date-right?-and

"in" for the widest situations of all, more than one day or one date.

Now, let's do a little practice to see how well you've understood this.

Okay, now let's fill in the blanks with our three words: "at", "on", and "in".

But before we fill them in here, let's fill them in on our triangle.

So, do you remember: What goes at the top, what's very narrow and covers a very specific time?

"At", very good.

What's a little bit more than that, covering one day or one date?

"On", very good.

And what's the widest of the lot, covering months, and seasons, and years, and decades,

Now let's apply what we've learned, because otherwise there's no point, so let's do it.

So: "_______ 6:00."

What do we say?

Do you remember?

"At 6:00."

"_______ Sunday."

One day, right?

"_______ winter."

What do we say?

It's a long period of time, especially in Canada where I live, okay?

So: "In winter."

We can also say: "In the winter."

And: "_______ Independence Day."

It's one day, so we need to say: "On Independence Day."

Now let's continue to some sentences, because that's how you actually use the language.

Number five: "See you _______ noon."

"See you..."

Now, what's "noon"?

"Noon" means 12 o'clock in the afternoon, it's a precise, exact time, so we say: "See

Number six: "I'll call you _______ Friday."

"I'll call you on Friday."

Very good, because it was one day.

Next one: "We have a meeting _______ 4:30."

"We have a meeting", specific time, which one? "...at 4:30".

And the last one: "They're getting married _______ March 9th."

It's one day, okay?

So, it is this one: "They're getting married on March 9th." Okay?

So, you can see that the triangle can help you to remember which preposition to use when.

Now, here's some more things you can do to help you remember this really, really well.

First of all, go to our website at www.engvid.com, and there you'll find a resource which I've

written which explains all of this, and also you can print it out, you can download it

Everything is for free; no cost. Okay?

And there you'll find exercises and explanations of this, and also an explanation of some exceptions

and expressions that we use with "at", "on", and "in".

There are about more than 50 of them. Okay?

So you'll find the explanation of the triangle, plus more.

Second, while you're at the website, www.engvid.com, you'll find hundreds of other lessons which

can help you with your English. Okay?

Lots and lots of lessons at different levels; beginner, intermediate, advanced, business

English, pronunciation, grammar, IELTS, TOEFL, you name it. Okay?

It's all available and it's all for free.

And last, before you go away, don't forget to subscribe to my YouTube channel so you
