The grammatical words which play so large a part in English grammar are for the most part sharply and obviously different from the lexical words. A rough and ready difference which may seem the most obvious is that grammatical words (1)______ have "less meaning", but in fact some grammarians have (2)______ called them "empty" words as opposed in the "full" words of 　(3)______ vocabulary. But this is a rather misled way of expressing the (4)______ distinction. Although a word like the is not the name of something as man is, it is very far away from being meaningless; (5)______ there is a sharp difference in meaning between "man is vile" and "the man is vile", yet the is the single vehicle of this 　　 (6)______ difference in meaning. Moreover, grammatical words differ considerably among themselves as the amount of meaning they 　　 　(7)______ have, even in the lexical sense. Another name for the grammatical words has been "little words." But size is by no mean　　 (8)______ a good criterion for distinguishing the grammatical words of English, when we consider that we have lexical words as go,　　 　(9)______ man, say, car. Apart from this, however, there is a good deal of truth in what some people say: we certainly do create a　 great number of obscurity when we omit them. This is illustrated (10)______ not only in the poetry of Robert Browing but in the prose of telegrams and newspaper headlines.
