Lady Macbeth

• Glamis thou art, and Cawdor, and shalt be What thou art promised; yet do I fear thy nature / it is too full o'th'milk of human kindness.

  Follows the same structre as the witches prophecy implying she has her own psychic abilities and assaciating with supernatural beings. The noun nature alludes to Macbeths motal soul and is recognised as kind. She continues to portray his kindness as an unfavourable trait to have. Milk connotes breastfeeding and so associates human kindness with femininity which presents compassion as a weakness and emasculating Macbeth.
• Come you spirits That tend on mortal thoughts, unsex me here and fill me from the crown to the topfull Of direst cruelty

  Willing to sacrifice herself to whatever evil spirits to help reach her goal. The use of anatomy makes her speech uncomfortable and illustrating how she wants to mutate into something else. She is asking to be rid of the parts that make her a women. Shakespeare implies gender is a sign of humanity, by being unsexed she would be removed from humanity and free her form the burdens and weaknesses of morality and conscience.
• Look like the innocent flower But be the serpent under't

  innocent flower highlights the goodness but also vulnerability of honest human behaviour. Serpent is a biblical reference to the serpent in the garden of eden. the audience links this with the devil. She would rather act like the devil than a moral human being.
• And take my milk for gall

  wants her nurturing and kind qualities to be corrupted, she takes images of stereotypical femininity and subverts them such as asking her breast milk to become poison.
• but screw your courage to the sticking-place, And we'll not fail
