Act 1 Scene 1: My thought, whose murder yet is but fantastical,
Shakes so my single state of man that function
Is smother'd in surmise, and nothing is
But what is not. (1.3.9)
After the witchs' prediction (which did not include murder) McBeth can't function properly because his thoughts/actions are being "smothered" by his imagination. The only thing that is real is that he wants to murder McBath and get the crown. This is the beginning of McBeth's downfall.
When Macbeth refers to Macduff he is talking about a man who holds the title Thane of Fife.
Eventually he is going to be beheaded. Is that what you are talking about?
"Smothered" in Spanish is "sofocado". If you are talking about a female, it is "sofocada". It is pronounced "so-fo-CAH-doe" or "so-fo-CAH-dah". Please see this site for confirmation of the translation: http://www.answers.com/library/Translations
In Act 2 Scene 1, Macbeth is onstage and Lady Macbeth is not. I think Macbeth in Act 1 Scene 5 is heading back to his castle called "Inverness" to talk to his wife (Lady Macbeth) about what happened with the witches and to come back from the war that just happened. Possibly you were thinking of Act 2 Scene 2 where she is talking and he is stabbing Duncan.
Duncan's guards.
who are you talking about?
Macbeth was talking to the murderers he hired to kill Banquo when he said, "Worms that fled." He was expressing his anger and frustration that Banquo's murderers only killed Banquo and let his son, Fleance, escape.
Lady Macbeth meaning to the ornament of life can be refer to the golden opinions of line 33. It could even be refer to the crown.
She faints. Killing the servants was not part of her plan. She now is beginning to realize that she has opened a can of worms by talking her husband into committing murder.
Apparently it's a superstition that it will bring bad luck to the theatre. Personally I think that it isn't true. I was reading Macbeth and talking about it at my rehearsal for a play and it went swimmingly.
This must be Act I scene 4 that we are talking about. The king has just announced that the party is at Macbeth's place, and so everyone is headed to Inverness.
Macbeth [d. August 15, 1057] didn't request Banquo's presence anywhere after talking to the three witches. He spoke to the witches in Act 4 Scene 1. Banquo already was dead at that time. The three murderers had killed him in Act 3 Scene 3. Instead, Macbeth requested Banquo's presence at a banquet after the murder of King Duncan I [d. August 14, 1040] and Macbeth's coronation the next day at Scone. This request was well after the first meeting of Banquo and Macbeth with the three witches.
