Hi everyone! Thank you for tuning in to Time for English.

Last week, I talked about synonyms. Today, we're going to look at antonyms. Antonyms are the opposite of synonyms.

If two words are antonyms, they have opposite meaning.

For example, the opposite of HOT is COLD. The words "hot" and "cold" are antonyms. Likewise, "happy" and "sad" are antonyms. "Fantasy" and "reality" are antonyms.

Now, you can often form antonyms by adding a prefix to a word, such as "un", "in", and "dis". For example, "agree" and "disagree", "connect" and "disconnect"; "formal" and "informal", "efficient" and "inefficient"; "able" and "unable", or "user-friendly" and "user-unfriendly".

When you learn a word, learning its synonyms and antonyms together is a great way to improve your vocabulary.

Now. Would you like to try a quiz? I'll give you three pairs of words. Please listen carefully and choose the correct pair of antonyms. Ready?

1. effective and uneffective

2. honest and dishonest

3. important and disimportant
