explain the significance of the line from shakespeare's macbeth - "double, double toil and trouble"
user
the phrase "double, double, toil and trouble" is spoken by the three witches in macbeth and creates a sense of mystery and foreboding. the repetition of the words "double" and the use of "toil and trouble" creates a sense of performing dark magic, as the witches concoct a potion to help macbeth achieve his ambitions.
