Different occupations, however, differ 【B7】 in their special vocabularies. It 【B8】 largely of native words, or of borrowed words that have 【B9】 themselves into the very fibre of our language. 【B10】 . though highly technical in many details, these vocabularies are more familiar in sound, and more generally 【B11】 . than most other technical terms. 【B12】 every vocation still possesses a large 【B13】 of technical terms that remain essentially foreign, even 【B14】 educated people. And the proportion has been much 【B15】 in the last fifty years. Most of the newly 【B16】 terms are 【B17】 to special discussions, and seldom get into general literature or conversation. Yet no profession is nowadays, as all professions once 【B18】 a close federation. What is called "popular science" makes everybody 【B19】 with modern views and recent discoveries. Any important experiment, 【B20】 made in a remote or provincial laboratory, is at once reported in the newspapers, and everybody is soon talking about it. Thus our common speech is always taking up new technical terms and them commonplace.
