oid world and new world

These days, young people’s word change. They create new words every year, every day, every time. Changing popular words every time. Perhaps your words which you use these days will become popular words. You fail to check young words carefully if you may older people.
The difference between young people and older people is big. It is difficult to understand young people’s words for older people. Equally, young people can’t understand older people’s words. Older people’s words are thought to be formal for young people. Of course, they have dialect, but their words almost haven’t change. However, young people’s words various changes. I’ll introduce some examples. First, “yabai(やばい)” “meccha(めっちゃ)” “bari(ばり)” the origin of these words is a dialect. “meccha” and “bari” means “very” in English. So, “meccha samui(めっちゃ寒い)” means “It’s very cold.” Second, “KY” is arrange words initial and make new word like sing. May be, young people get tie simply by common sign, and they feel pleasure of using these words. While, below words are use adults. “convini(コンビニ)” is abbreviation of “convenience store” another one is “keitai(ケイタイ)” is “keitaidenwa(携帯電話)” These abbreviated words have already penetrated wide generation. Formal words are no longer in current use except write criticism and news. Maybe the newest word in Japan is “kimo-kawaii(キモかわいい)” This word made negative word and affirmative word. It give good effect on friendly, people who are negative people. So, “kimo-kawaii” means disagreeable but cute. “dasa-kakkoii(ダサかっこいい)” means unfashionable but cool. That’s why these two opposite words make new positive meaning words.
The above meaning words are created by young people. Especially who go to high school girls. They use these words and take up media. Finally, new word spread all over the Japan. Now, Japanese trend is copied by teenagers. Recently, these abbreviated words don’t understand for a lot of people. But, these words give the dictionary as new words. Perhaps new words become common language and everyone use new words after some years. Everyone should check media carefully, or you shall be outdated man.
