In every cultivated language there are two great classes of words which, taken together, comprise the whole vocabulary. First, there are those words -1- which we become acquainted in daily conversation, which we -2-,that is to say, from the -3- of our own family and from our familiar associates, and -4- we should know and use -5- we could not read or write. They -6- the common things of life, and are the stock in trade of all who -7- the language.Such words may be called "popular", since they belong to the people -8- and are not the exclusive -9- of a limited class. On the other hand, our language -10- a multitude of words which are comparatively -11- used in ordinary conversation. Their meanings are known to every educated person, but there is little -12- to use them at home or in the market-place. Our -13- acquaintance with them comes not from our mother's -14- or from the talk of our school-mates, -15- from books that we read, lectures that we -16-, or the more -17- conversation of highly educated speakers who are discussing some particular -18- in a style appropriately elevated above the habitual -19- of everyday life.Such words are called"learned", and the -20- between them and the"popular"words is of great importance to a right understanding of linguistic process.
