The list in the previous section might help, but it is not enough for you to learn how to spot and use these two word types. First, you'll need to learn to recognize them. Let's look at adjectives first:
The first two questions are questions you can ask when trying to find the adjective. In the phrase "the red car", the car is the noun. The car is, in these questions, the thing. So, if you ask "What kind of car?", the answer is "a red one". If you ask "Which car?", the answer is "the red one". Both help you see that red, in this phrase, is the adjective.
These two questions work most of the time, but not always. Sometimes, adjectives describe things like emotions, feelings, compliments or insults, shape or color, and more. One thing that helps in these cases is replacing the verb with a form of "to be".
In the sentence "Francine seems happy", try taking out the word seems and putting the word is in its place. "Francine is happy" still makes sense, meaning that happy describes Francine. This tells you that you've found an adjective.
