day for 30 days. You're learning 105 words from  the academic word list, words you'll need to know  

if you're preparing for the IELTS or TOEFL exam,  but also if you read or watch the news in English,  

or have conversation with native speakers. These  are intermediate words, very much so a part of  

everyday conversation. We're going to study  them in real situations so your understanding  

will go beyond simply memorizing a definition. So  grab your friends, have them join the challenge,  

and let's do this. As always, if you like  this video or you learned something new,  

please like and subscribe with notifications.  I'd love to have you as my student.  

During these 30 days, we're learning 105  words together. I do have a download for you,  

a list of all the words with definitions and  sample sentences, as well as quizzes to make  

sure you're really getting and remembering these  words. You can get that download by following  

this link or the link in the video description. Our first word today is CATEGORIES.

A four syllable word with first syllable stress with  that AA vowel there: caa-- caa-- cate-- cate--  

categories. Categories. It's a noun, groups of  people or things that are similar in some way.  

Bodybuilders compete in categories  according to their weight.  

Let's look again up close and in slow motion. 

And now we'll go to Youglish to see  five examples of this word in context. 

Those are the five categories  that they're looking at. 

Categories. Types or subgroups. An everyday  encounter with categories is types of food,  

fruits, vegetables, carbohydrates, proteins,  and so on. These are food categories. 

Those are the five categories  that they're looking at. 

Here's another example. The way that we look at it  

is there's sort of two categories of  films that we'll be making in the future. 

Categories of film. He's talking about  

one, blockbusters, when producers  have lots of money to spend, and  

two, independent films, lower budgets, they  tend to be very unique. Two different groupings. 

The way that we look at it is there's  sort of two categories of films  

that we'll be making in the future. Let's see another example. 

But they're right here in these  four categories, solve a problem,  

getting started, how to and troubleshooting. It sounds like he's talking about a user  

manual. I recently got a new TV, I love it,  but it did come with a really big manual,  

a big setup book, and there were different  categories about the kinds of information  

where you would find what type of information. But they're right here in these four categories,  

solve a problem, getting started,  how-to, and troubleshooting. 

Let's look at another example.

So we've created new categories. 

Did your school give away awards to students? I  remember a few of the categories, science star,  

spelling champ, and so on. So we've created new categories. 

Our last example. So I created an easy diagram that separates these  

guys into five different analysis categories. Analysis categories. Her graph shows data on  

bees. It compares size to how far they can fly  before needing food. Grouping based on size.

Our next word is one you're likely really  comfortable with, but let's make sure you're  

also comfortable with the pronunciation, it's  COMPUTER. Your first syllable should be very  

short, it should feel like there's no vowel  there. Com-- com-- Computer. Puter-- rarara--  

It's a flap T, your tongue just does one quick  flap against the roof of the mouth. Computer.  

Computer. Now for that ending schwa R ending,  rrr-- you don't need a whole lot of lip rounding,  

a whole lot of lip flaring. The lips are more  relaxed when the R's at the end, but the tip  

still does need to pull back a little bit so it's  not touching anything. Ter-- ter-- ter-- Computer.  

It's a noun, an electronic machine that can  store and work with large amounts of information.

And now we'll go to Youglish to see  five examples of this word in context. 

Computer generated movies  are really mainstream today. 

Computer generated is a compound adjective.  Somebody used software on a computer to animate  

characters or a scene in a movie. In my early  childhood, computer generated images were not the  

norm in movies. Now, they are, they're mainstream.  We see them all the time. We expect them.

Here's another example. I had no phone, no computer. 

Do you hear the rising intonation  at the end of phone and computer?

I had no phone, no computer. Let's see another example. 

Turn off your phone, turn off your  computer, and listen to your true heart. 

These days, that's easier said than done. I  do find that it's easier for me to make big  

important decisions by taking some time to be  still and quiet, no technology, just spending  

some time asking myself what I really want. Turn off your phone, turn off your computer,  

and listen to your true heart. Let's look at another example.
