 Moving further down our list of parts of speech, we have our adjectives. Adjectives modify or describe nouns. Basically, they give more information about the noun. Here, we've used a noun such as chair. It can be any old chair. It's only the noun. If we want to describe the noun, we need to use an adjective before it. So, I could say I have an old black leather chair. Here, we have to be concerned about the adjective order. In this instance, I started with age, as age typically goes before color. And then I used a color to go before the material. This is a certain pattern. Depending on the adjectives you want to use, you always have to use certain patterns to which you'll need to be aware of when teaching your class. Another way to describe a noun is by showing possession. We do so by using our possessive adjectives. Earlier, we used the example of chair as the noun. We talked about it in terms of age, material, etc. Now, we could add words such as my, your, his, her, its, our and their also to describe the chair. It's my chair, or it's her chair, or it's our chair. These are not to be confused with possessive pronouns, which of course we'll get into in just a moment. In forming our comparatives and our superlatives, we always have to be concerned with spelling patterns. With one syllable adjective such as fast and old, where we have two consonants at the end, we simply add our er or our est. However, with one syllable adjectives, where the pattern is consonant, vowel, consonant, we have to double our final consonant before adding er or before adding est. Now, with two syllable adjectives that end in y, we drop our y and add i-e-r or i-e-s-t. However, with all other two syllable or three syllable adjectives, we don't simply put er or est at the end. We'll typically keep the adjective as the same adjective, here modern, but in order to make the comparative, we'll add more before modern. And when forming the superlative, we'll put the most before the adjective modern. And finally, when looking at our comparatives and superlatives, we must be aware that there are some irregular comparatives and superlatives. Two of the most common are the adjective good, changing to the comparative better and to the superlative the best. We also have the adjective bad, changing to the comparative worse, and the superlative the worst.
