In our previous several papers,we examined negative expressions in Richardson's epistolary novels mainly from the viewpoint of ''word-formation." our last paper,in particular, was devoted to considering his use of un-words. The present paper continues to discuss negative expressions further in the perspective of word-formation. This time our focus is put on the analysis of "Compounds" used as negation(including quasi-negation"). The analysis is made in three substantial sections; the first two sections provide some representative examples, with the remaining one confined to the discussion of the author's technique as a word-maker. In the process of summing up Our discussions, We hope to point out his linguistic influences on Jane Austen, aprominent female writer of the coming generation.
