Macbeth's letter to his wife by William Shakespeare starts telling of the witches prophecies and of his promotion to the Thane of Cawdor. The first line "They met me in the day of success" displays the alliteration of the sound "m" and it focuses the attention of the reader on Macbeth's position. It is also reinforced by the subject "I" in the following sentence. Right from the start the intelligent reader can understand that Macbeth believes in the supernatural by the words "the perfectest report" and "mortal knowledge". in the second line, the adjective " perfectest" underlines the Macbeth's belief in prophecies. The alliteration of the sound "t" in the third line wants to draw the attention on the witches and on their important role. Shakespeare uses the verb "burned" to make the reader understand he wants to know about his future. Indeed the writer uses the form "stood rapt" in place of "was surprised" to draw the attention on his reaction. In the seventh line, the verb "all-hailed" underlines the importance of the title "Thane of Cawdor".

Therefore immediately Macbeth writes a letter to his wife to tell her what happened to him. The intelligent reader understands that Lady Macbeth is crucial for Macbeth's future as visible in "my dearest partner of greatness". The words "dear" and "great" reinforces the kin's courtesy and the delight to write to his wife. The letter reveals his love and his trust for his wife. In line 12, "thou mighst lose the dues of rejoicing", the reader understands that Macbeth believes in his dreams. In addition, he announces to his wife to be joyful because she will be a queen. Macbeth doesn't have a right behaviour and he reminds a child. His wife has a strong influence on him and she is responsible of Macbeth's actions and passions. The repetition of the sound "you" in the last lines underlines his second position. His wife really describes everything.

The second part of the text, from line 15, describes Lady Macbeth's ambition and opinions, at the same time revealing Macbeth's and his wife's personality. Right from the first appearance Lady Macbeth is presented with a devilish nature: she incites his husband to murder the current king. She wants to transform the witches' prophecies into concrete facts. She is the dominant partner in the marriage and she plays his husband along. In the sixteenth line, the word "fear" underlines that Lady Macbeth suspects her husband isn't really good.in addition she enables him to do what needs to be done. The syntactical order "yet do I" underlines the fear of Macbeth too. The sentence "it is too full o' the milk of human kindness" is a metaphor to compare Macbeth to a baby who needs to be supported. The repetition of the phonological sound "u" underlines the seriousness of the situation. Therefore lady Macbeth has a relevant role. This is strange because in the Middle Ages the woman wasn't as important as the man. In this case, the man is manipulated by the woman.

Lady Macbeth suggests to "the nearest way" because her husband is coward and he hasn't the right "stuff" to reach the throne. In the last lines the writer reinforces the important role of Lady Macbeth because she influences her husband.
