Find unusual words from the speech by Shakespeare below

Why, I, in this weak piping time of peace,
Have no delight to pass away the time,
Unless to spy my shadow in the sun
And descant on mine own deformity:
And therefore, since I cannot prove a lover,
To entertain these fair well-spoken days,
I am determined to prove a villain
And hate the idle pleasures of these days.
Plots have I laid, inductions dangerous,
By drunken prophecies, libels and dreams,
To set my brother Clarence and the king
In deadly hate the one against the other:
And if King Edward be as true and just
As I am subtle, false and treacherous,
This day should Clarence closely be mew'd up,
About a prophecy, which says that 'G'
Of Edward's heirs the murderer shall be.
Dive, thoughts, down to my soul: here
Clarence comes.
