The different pronunciations of the same word.
Here is my record. [ rek d]
I’ll record this for you.[r k d]
Complete the passage with the help of word formation.
When you open a dictionary, you often come across a lot of unfamiliar words. You might think this is a bit scary. But many of them are formed using other simpler words. This is called word formation.
Words formed by combining other words are called compounds, for example, 1___________(a friend that you contact by writing, traditionally using a pen) and 2_____________(known by many people).
Prefixes and suffixes often have fixed meanings.If you add un-or in-to a word, the new word usually means the opposite. For example, if something isn't corect its 3_____________, and if someone isn't happy they're 4___________. Words with the suffixes-ment and -ness are often nouns. For example, if somebody has improved a lot, they have made great 5 ______________.
penfriend
well-known
incorrect
unhappy
improvement
Some nouns and adjectives can be used as verbs, or the other way round. When we calm somebody down, they become 6________. And we can give someone a present by 7__________it.
And sometimes a word ismade up of the first letters of several words:"World Trade Organization" can be referred to as 8________and 9_________ is short for "as soon as possible".
It is impossible to know the meaning of every word, but knowing about word formation can help us guess their meanings.
calm
presenting
WTO
ASAP
Homework: Work in groups. Choose one type and come up with as many words as possible.
Group A
Group B
Reflection: After this class, I can rate my performance 1(excellent), 2(good), or 3(in need of improvement).
