How many words do you know that mean 'happy'? What about 'sad'? In today's lesson you'll learn LOTS of different ways to describe how you're feeling. When you're learning a language, it's important to have a broad vocabulary. Whether you're writing an essay or you're speaking with your boss, using more interesting and expressive vocabulary will make your sentences clearer, and you'll sound more intelligent, too. Try using the adjectives in this lesson instead of ordinary ones at work, school, or in the writing and speaking sections of exams like the IELTS, TOEFL, or CAE. You'll also learn some common expressions and idioms that native speakers use to talk about their mood, like "over the moon", "happy bunny", and "down in the dumps".
