This study adopts the theory of conceptual metaphor in order to explore William Shakespeare’s play, Macbeth. More specifically, it records the metaphorical expressions which are built upon conceptual metaphors in which the source domains PATH and CONTAINER are identified. The author claims that these source domains instigate the dramatic linguistic effect of Macbeth from the beginning to the end, structuring the plot and the characters. The analysis provides a better comprehension of the play by uncovering the various philosophical, psychological, and cognitive aspects of it.
