There are two purposes of this research. It is to clear the matter whether what kind of technical term flows in newly in the vocabulary which a modern uses with life, and one is to analyze the matter whether one more characteristic of what kind of change is seen in that vocabulary. The vocabulary of the readers' column of the newspaper was investigated for that.The first of what became clear from the result of the investigation is that a technical word exists in the word which use frequency is small in. Most of those words were the katakana words which contained many loanwords.The second is that there are many technical new words in the social word. It is because there are many words related to the media in the loanword which use frequency is large in, and social words. A word such as medical science which the other side, use frequency are small in, an economy and social welfare is because there are a social problem and a substitute, too. It can expect that the new word of the technical term is generalizing with the social problem from the above.When a technical term became a daily word, it became clear that there were many things flowing in fundamentally like a loanword as a new general idea from the outside in the third. Then, use frequency is small, and it can think with the candidate of the technical term which a loanword to change, the social problem makes a daily word.
