i write this post to remember what i learn and i make this own example.
a prefix is a small part of a word, usually just a couple of letters, that we put at the front of a base word to change its meaning.
Here are the prefixes and examples used in the programe:
un -
unhappy
the fans were very unhappy when the artist sick
uncooked
i can't eat these uncooked pie. they are very sour
unclean
that air is unclean. we will sick if breath here
other words with un - : unconfortabe, unhygienic
in -
intolerable
this heat is intolerable. it's making me feel ill
inexpensive ==> cheap
the shop sells inexpensive table phone
inactive
he's put on weight because he is so inactive. He should join a gym
dis -
disagree
i disagree with my girlfriend what we will watch in cinema
disgrace ==> (ashamed of -> memalukan)
your attitude is a disgrace
disguting (horrible -> menakutkan / menjijikan)
there's a disgusting smell in the bathroom
other prefix : misleading (menyesatkan); mistake (kesalahan)
tips:
if you look up some today's words in a dictionary, you'll find lots more words starting with the same prefixes. Many of them may be words that you already knew without the prefix. So, when you add a prefix, you get two words for the price of one.
