Hello, my name is Amelia. In this video, we will look at how to take words you already know and make them into new words. All you have to do is add a few letters before the word—these are called "prefixes." Or, add a few letters after a word—these are known as "suffixes."
Here's an example: "Place," "re"-place, replace-"ment." Be careful. You can't do this with all vocabulary, but you can have fun experimenting to see which ones work and which ones don't.
Let's look at prefixes first. We all know the word "do." Did you know that you can "re"-do something? And if you're not happy with it, you can "un"-do it too. What does the prefix "re-" mean here? That's right. "Re-" means "again." So if you "redo" something, you do it again. And what about "un-" in "undo"? "Un-" is an opposite. So if you "undo" something, you reverse what you have done. Here's another prefix. What does it mean? "Dis"-agree, "dis"-like, "dis"-allow, "dis"-appear. "Dis-" also means "not" or "reversal."
先來看字首。我們都知道 do(做)這個字。你知道你可以 "re"-do(重做)某件事嗎？如果你不滿意，你也可以 "un"-do(取消)它。這的字首 re- 是什麼意思呢？沒錯。Re- 代表「再一次」。所以如果你 redo 某件事，就是你再做那件事一遍。那麼 undo 中的 un- 呢？Un- 則相反。如果你 undo 某件事，你整個改變了你做過的事。這有另一個字首。它是什麼意思？"Dis"-agree(不同意)、"dis"-like(不喜歡)、"dis"-allow(不允許)、"dis"-appear(不見)。Dis- 也代表「不」或「相反」。
Now let's look at some suffixes. "Happy" is an adjective. How can we make it into a noun? Simple. Just add the suffix "-ness." "Happy" plus "-ness" equals "happiness." Here are two more adjectives to express feelings: "sad" and "tired." To make the noun, you just add the same suffix. Have a look. "Sad" plus "-ness" equals "sadness." "Tired" plus "-ness" equals "tiredness."
現在我們來看一些字尾。Happy(開心的)是個形容詞。我們怎麼把它變成名詞呢？簡單。只要加上字尾 -ness。Happy(快樂的)加上 -ness 等於 happiness(快樂)。這還有兩個表達感受的形容詞：sad(憂傷的)和 tired(疲累的)。要變成名詞，你只要加上相同字尾。來看看。Sad(憂傷的)加上 -ness 等於 sadness(憂傷)。Tired(疲累的)加上 -ness 等於 tiredness(疲累)。
There are a few more prefixes and suffixes that go with a range of words. Learning which ones to use and with which words may seem hard at first, but with time, you'll learn to hear what sounds right. Prefixes and suffixes are everywhere. Next time you're reading or listening to English, start noticing which beginnings and endings are being used. Make a note of them, and more importantly, use them—it's the only way to remember them.
We hope you found this video helpful, and we look forward to your return. Thanks for watching.
