Hamlet, Prince of Denmark
(Auto-generated)

This is for all:
I would not, in plain terms, from this time forth
Have you so slander any moment leisure
As to give words or talk with the Lord Hamlet.†
p. 47.9 *

slander = lie in such a way as to damage the reputation of another; or the lies told
Slanders, sir; for the satirical rogue says here that old men have gray beards, that their faces are wrinkled, their eyes purging thick amber and plum-tree gum, and that they have a plentiful lack of wit, together with most weak hams; all which, sir, though I most powerfully and potently believe, yet I hold it not honesty to have it thus set down; for yourself, sir, shall grow old as I am, if, like a crab, you could go backward.†
p. 95.7
