No other comedy among Somerset Maugham’s dramatic works has gained greater popularity than Our Betters (N.Y., 1917; London, 1923).  Since its première both in New York and in London, Our Betters has been a controversial play, and attracted a range of opinions, but little attention has been paid to stylistic analysis of the dialogues in the play.  Thus it is worthwhile considering the speeches comprising the dialogues and examining their linguistic features.  In order to explore these issues, this paper attempts to analyze the arrangement of the speeches in the dialogues and three levels of linguistic features in the speeches: word, meaning unit and clause levels.  As for the analysis of the speech arrangements, it is necessary for us to categorise 1,625 turns of speech into the twenty-three utterance content types, and then to give consideration to how the playwright arranges these different types of speeches in order to develop his dialogue.  In terms of the linguistic features in the speeches, an analysis of words, meaning units and clauses gives us a path to understanding what linguistic manipulation Maugham uses to make a speech vivid and impressive in the given context of a dialogue.
